Thank you, Todd. And thanks everyone for joining us today. I'll first discuss some housekeeping items. Then I'll discuss our business metrics and financial results. And lastly, I will review our forward guidance. Note that unless otherwise stated, all financial results in my discussion are non-GAAP based. We are always focused on providing the most useful business metrics that help investors understand the fundamentals of our business and our progress toward our goals. Beginning with the first quarter of 2024, we will discontinue disclosing quarterly NRR and DBNER, as well as our market, countries, and bandwidth statistics. We believe these were used infrequently by the investment community and candidly weren't particularly helpful in understanding our business. Finally, we will begin disclosing revenue by product area, split between core, growth, and emerging products. Specifically, the core segment includes our delivery and network services. The growth segment includes our security offering. And the emerging segment includes our compute and observability offerings. Again, these will commence with our next quarter earnings release and we'll provide further details at that time. Turning to our financial results, revenue for the fourth quarter increased 15% year-over-year to $137.8 million. Coming in at the lower end of our guidance range of $137 million to $141 million. Revenue from Signal Sciences products was 13% of revenue, a 25% year-over-year increase, or 24% increase excluding the impact of purchase price adjustments related to deferred revenue. Also, note that we calculate growth rates off the actual results with the percentage of revenue rounded to the nearest whole percent. In the fourth quarter, we saw traffic expansion at our major customers, coupled with healthy upsell and cross-selling activity. However, we saw weaker international traffic in the fourth quarter, a reversal from what we saw in the third quarter, resulting in lower revenue growth, but higher gross margins, which I'll touch on in a moment. Our annual revenue was $506 million, representing 17% growth over 2022, and coming in above our original guidance range of $495 million to $505 million provided one year ago. For the fourth quarter, RPO was $245 million, down 1% from $248 million in the third quarter of 2023, and up 24% from $198 million in the fourth quarter of 2022. As our consumption-based revenue model is now being augmented with predictable revenue packages, we believe that RPO will become a more meaningful indicator to the health of our business in 2024. As Todd shared earlier, we had 3,243 customers at the end of the fourth quarter, of which 578 were classified as enterprise, a net increase of 31, compared to a decrease of four in the third quarter, and an increase of 22 in the fourth quarter of 2022. Our trailing 12-month net retention rate was 113%, down from 114% in the prior quarter, and 119% in the year ago quarter. Our annual revenue retention rate, which we reported fiscal year-end, was 99.2% for 2023, up from 98.9% in 2022. These figures continue to reflect our very low churn and healthy customer retention dynamic. Enterprise customers accounted for 92% of total revenue on an annualized basis in both Q4 and Q3, with average enterprise customer spend of $880,000, up 3% from $858,000 in the previous quarter, and up 7% from $822,000 in Q4 of last year. Our top 10 customers comprised 40% of our total revenues in the fourth quarter of 2023, flat with their contribution in Q3, reflecting in part the impact of vendor consolidation and expansion of traffic in some of our largest customers, which also drove one customer to account for more than 10% of revenue in the fourth quarter. I will now turn to the rest of our financial results for the fourth quarter. Our gross margin was 59.2% in Q4, compared to 55.9% in Q3 of 2023, well above our expectations of a 100 basis point sequential increase. As I noted in my discussion of fourth quarter revenue, we saw weaker international traffic in the fourth quarter, a reversal from the stronger international traffic we saw in the third quarter, which resulted in lower revenue growth, but had a positive impact on our gross margins. Our team also executed on controlling our variable cost of revenue, especially with lower transit costs, with successful renegotiation of our transit rates in several international markets. As Todd explained, we recognized the one-time $2.8 million take or pay true up payment that benefited gross margins in the quarter. Had this benefit not been reflected, gross margin would have been 58.3% in the fourth quarter. Our 2023 annual gross margin was 56.9%, up 330 basis point over 2022's gross margin of 53.6%. Discounting the benefit of the $2.8 million true up in the fourth quarter of 2023, and the $3.3 million true up in the fourth quarter of 2022, the gross margin improvement would have been 350 basis points year-over-year. I'm very pleased with the cross-functional work that took place in aligning our network capacity investments with expected traffic demand, our cost control efforts in bandwidth transit costs, and our progress in pursuing beneficial peering relationships. While we have made significant gains in our cost of sales, there is still room for further improvement as we scale, and we remain committed to demonstrating an 80% incremental gross margin in our financial model going forward. Moreover, the 330 basis point improvement in gross margin year-over-year, coupled with 17% revenue growth, resulted in gross profit growing by $56 million, or 24% over 2022. Operating expenses were $84 million in the fourth quarter, a 5% increase compared to Q4 2022, and sequentially flat with the third quarter. Our operating expenses were lower than expected due to continued cost management efforts and fourth quarter hiring coming in slightly below our expectations. Recall that our sales and marketing expenses in the third quarter were impacted by one-time marketing expenses related to events and fees, which benefited the sequential comparisons and OpEx. This favorability, combined with gross profit ahead of expectations, resulted in an operating loss of $2.3 million in the fourth quarter, exceeding the high end of our operating loss guidance range of $10 million to $6 million. For 2023, our total operating expenses were $325 million, up 5% from $308 million in 2022. Given our revenue and gross profit growth rates of 17% and 24%, respectively, we were able to leverage our lower OpEx growth to reduce our operating loss margin by more than half, from 17.7% in 2022 to 7.2%. The majority of our OpEx progress was due to company-wide financial rigor we've discussed over the course of the year, including notable larger items such as reducing duplicative or unnecessary SaaS and IT tools in our organization. In the fourth quarter, we reported a net profit of $1.7 million, or $0.01, per diluted share, compared to a net loss of $9.5 million, or an $0.08 loss per basic and diluted share in Q4 2022, demonstrating our ability to drive towards sustainable profit in our business. Our adjusted EBITDA was positive in the fourth quarter, coming in at $11.5 million, compared to negative $0.1 million in Q4 2022. I'm pleased to report that our 2023 full-year EBITDA was positive $15.5 million, compared to negative $32.9 million in 2022. Turning to the balance sheet, we ended the quarter with approximately $329 million in cash equivalent, marketable securities and investments, including those classified as long-term. We continued our repurchase of convertible debt principle in the fourth quarter, resulting in a reduction of our convertible debt principle balance by more than 50% from $713.8 million at the end of 2022 to $346.5 million at the end of 2023. And specifically in the fourth quarter, we repurchased $130.9 million in principal amount of our convertible notes for $113.6 million in cash or approximately $0.87 on the dollar. Coupled with a larger repurchase back in May, our 2023 repurchases totaled $367.3 million in principal for $310.5 million in cash or approximately $0.85 on the dollar. Our free cash flow for the fourth quarter was negative $21.9 million, a $2 million sequential decline from negative $19.7 million in the third quarter. This decline was primarily driven by an increase in our capital expenditures compared to the third quarter. Our 2023 free cash flow improved by $113 million over the prior year to negative $59 million from negative $172 million in 2022. This year-over-year improvement was driven by approximately a $70 million increase in cash from operations and a $42 million reduction in advanced payments for equipment. Our cash capital expenditures were approximately 11% of revenue in the fourth quarter and totaled 8% for 2023, coming in at the high end of our guidance of 6% to 8% of revenue. As we shared on our Q3 call, we accelerated certain 2024 deployments into late 2023. As a reminder, our cash capital expenditures include capitalized internal use software. For 2024, we anticipate our cash CapEx will be in the 6% to 8% range with deployments to be weighted toward the first half of the year. I will now discuss our outlook for the first quarter and full year 2024. I'd like to remind everyone again that the following statements are based on current expectations as of today and include forward-looking statements. Actual results may differ materially and we undertake no obligation to update these forward-looking statements in the future except as required by law. Our first quarter and full year 2024 outlook reflect our continued ability to deliver strong top-line growth via improved customer acquisition and upsell and cross-sell expansion in our existing customers, driven in part by new and enhanced products. Our revenue guidance is based on the visibility that we have today. Similar to Q1 2023, we expect revenues to decline sequentially from our seasonally high Q4 results due to lower traffic patterns and the absence of the $2.8 million take or pay true up recognized in the fourth quarter. For the first quarter, we expect revenue in the range of $131million to $135 million, representing 13% annual growth at the midpoint. We continue to be very disciplined in our network investment and cost of revenues, which contributed to our fourth quarter gross margins being approximately 200 basis points better than we initially expected. We typically see a seasonal decline in gross margins in the first quarter with improvement in the second half as we build capacity for peak traffic. For the first quarter, we anticipate our gross margins will decrease approximately 100 basis points relative to the fourth quarter, plus or minus 50 basis points. As we mentioned previously, our Q4 operating loss was moderately better than our earlier expectations on continued cost management and slightly slower hiring. Our first quarter operating results will reflect the impact of the seasonal decrease in gross margins and the impact to our operating expenses of first half employer payroll tax increases. As a result, for the first quarter, we expect our non-GAAP operating loss to increase to a loss of $14 million to $10 million and our non-GAAP net loss to be $0.09 to $0.05 per share. For calendar year 2024, we expect revenue in the range of $580 million to $590 million, an annual growth rate of 16% at the midpoint. This guidance reflects our expectation for quarter and quarter acceleration and revenue growth through the year driven by new customer acquisition and continued expansion of existing customers. We expect to continue to see gross margin improvement in 2024 and to continue our spending discipline while increasing our investment in go-to-market and product development. We anticipate our 2024 gross margins will improve by approximately 200 basis points, plus or minus 100 basis points relative to 2023, and to exit the year with gross margins at 60% or better. As a result, we expect our non-GAAP operating loss to improve to a range of $20 million to $14 million, reflecting an operating margin of negative 3% at the midpoint, an improvement of over 50% over 2023's operating loss margin of 7.2%, and by over 80%, over 2022's operating loss of 17.7%. We expect our non-GAAP net loss per share to improve to $0.06 to break even, reflecting the improvement in our operating loss expectation. And we expect free cash flow to be break even in 2024, compared to negative $59 million in 2023. Before we open the line for questions, we'd like to thank you for your interest and your support in Fastly. Operator?
