Thanks, Paul. And as Paul just highlighted, our business performed well in the first quarter. Our revenue came in just above our guidance range at $276 million. That's up 15% year-over-year and down 3% sequentially. During the quarter, we saw a strong demand for our value-added services across all verticals, and as Paul mentioned, these services reached nearly 60% of our total revenue, now up four points compared to Q1 of last year. We also delivered year-over-year growth in our volume-driven solutions even with the impact of a significant number of renewals with some of our largest customers in Q1. Revenue from our enterprise vertical, which is our fastest-growing customer set, grew 31% year-over-year and 8% sequentially as our customers moved more of their business to the cloud. Our commerce vertical increased 25% over Q1 of last year. As expected, commerce revenue declined 8% compared to Q4, primarily due to the seasonality of our advertising division solutions. Revenue from our media and entertainment customers grew 15% year-over-year and declined 4% sequentially in the first quarter, driven by contract renewals at lower price points from some of our largest media customers. Value-added services revenue in this vertical actually grew 7% sequentially. High-tech vertical was down 3% year-over-year and down 3% on a sequential basis, driven by lower software download buys in Q1 compared to an elevated Q1 last year. We saw a continued traction among software-as-a-service customers purchasing our Application Performance Solutions, and value-added solutions now account for over 50% of the revenue in this vertical. On the public sector revenue grew 16% year-over-year in Q1 and also grew 2% sequentially. During the first quarter, sales outside North America grew to 30% of total revenue, up 3 points from the prior quarter. International revenue grew 5% sequentially and 22% year-over-year. The weaker dollar had a positive sequential impact of about $750,000, and on a year-over-year basis, the currency impact was favorable by about $3 million. And excluding the impact of currency, international revenue grew 17% on a year-over-year basis. Revenue from North America grew 12% on a year-over-year basis but was down 6% sequentially, driven by seasonality in our advertising solutions, as well as the large renewals which were predominantly in the U.S., and resellers accounted for 18% of total revenue consistent with the prior quarter. Our cash gross margin for the quarter was 80%, down a point from last quarter and down 3 points for the same period last year. GAAP gross margin, which includes both depreciation and stock-based compensation, was 68% for the quarter, down 2 points from the prior quarter and 4 points from last year driven by depreciation growth as we continue to invest in the platform. GAAP operating expenses were $114.1 million in the first quarter. These GAAP numbers include depreciation, amortization of intangible assets, stock-based compensation and acquisition-related charges. Excluding these noncash charges, our operating expenses for the quarter were $91 million. And that's down $9.7 million from Q4, a slightly larger decline than we expected as some expenses did slip from Q1 to Q2. Adjusted EBITDA for the first quarter was $129.2 million. That's up 9% from the same period last year and roughly consistent with Q4 levels. Our adjusted EBITDA margin came in at 47%, up 2 points from the prior quarter and down 2 points from our record level in Q1 of last year. For the first quarter, total depreciation and amortization was $41.1 million. And these charges include $32.7 million of network-related depreciation, $4.1 million of G&A depreciation and $4.3 million of amortization of intangible assets. Net interest income for the first quarter was $3 million, and that's roughly flat with fourth quarter levels and with Q1 of last year. Moving on to earnings, GAAP net income for the quarter was $50.6 million or $0.26 of earnings per diluted share. As a reminder, our GAAP net income includes several primarily noncash items including $17.8 million of stock-based compensation, including amortization of capitalized equity-based compensation, and $4.3 million from amortization of acquired intangible assets. We are including GAAP taxes in our normalized earnings, and that tax charge was $24.1 million for the quarter based on a full year GAAP tax rate of about 32%. Based on this methodology, our normalized net income for the first quarter was $72.2 million, up 9% from Q1 of last year and down 6% from Q4. In the first quarter, we earned $0.38 per diluted share on a normalized basis, $0.01 above our guidance range. That's up $0.03 from Q1 2010 and down $0.02 from Q4. Our weighted average diluted share count for the first quarter was 191.4 million shares. Cash generation continued to be very strong. Cash from operations for the first quarter was $88.5 million, and at the end of Q1, we had $1.26 billion in cash, cash equivalents and marketable securities on the balance sheet. Capital expenditures excluding equity compensation were $46.2 million. This number includes both investment in the network as well as capitalized software development. During the quarter, we spent $42.8 million in share repurchases, buying back about 1 million shares in an average price of about $42. From program inception in April of 2009 through last quarter, we spent a total of $201 million buying back just under 7 million shares at an average price of just under $30. And as Paul mentioned, our board has authorized an additional $150 million of share repurchases over the next 12 months. As a result, we expect to continue our buy-back program with the goal of using a portion of our operating cash flows to offset dilution from our equity programs. Finally, days sales outstanding for the quarter were 57 days. Q1 was a very solid start to the year. We saw a strong demand for all of our value-added solutions, and we expect continued adoption of these services as our customers expand their online businesses. As expected, we did see a moderation of traffic growth, and our volume-driven solutions off a very strong 2010, a trend we anticipate will continue in Q2. We're also projecting that the large volume-related renewals we had in Q1 will impact our second quarter revenue growth as well. We remain optimistic about the long-term growth for our volume-driven solutions, but it's still too early to predict the exact rate and pace of traffic growth for the rest of the year. Specifically for Q2, we expect revenue in the range of $270 million to $280 million or 10% to 14% year-over-year growth. At current spot rates, foreign exchange will be about a $3 million benefit on a sequential basis and about a $10 million benefit on a year-to-year basis. We expect cash gross margins to remain roughly stable at about 80% and GAAP gross margins to come in at roughly 67% to 68%. We also plan to continue investing in our long-term growth initiatives, as well as catch up on some of the investments that slipped out of Q1. We expect Q2 operating expenses to increase by about $7 million to $8 million from the prior quarter, which will include the annual impact of budgeted salary increases. The increased investments we expect adjusted EBITDA margins to come in at about 44% to 45%. We expect normalized EPS for the quarter of between $0.34 and $0.37. This includes the tax charge of between $17 million and $21 million based on a full year GAAP tax rate of about 32% to 33%. On CapEx, we expect to spend about $50 million in the quarter excluding equity compensation, and for the full year, we still expect CapEx to be at the upper end or slightly above our long-term model of 13% to 16% of revenue. We continue to get requests from some of you for us to provide specific annual guidance every quarter, so we're going to maintain our practice of only providing guidance on a quarter-by-quarter basis. In summary, we were very pleased with our Q1 performance. We were especially pleased with the overall strength of our value-added solutions, where we've seen increase in adoption as our customers rely on our expertise in leveraging cloud computing across their businesses. And while traffic growth in our volume business has moderated after a very strong year, we remain confident in the long-term growth potential of that business as well. Now let me turn the call back over to Paul.
