First of all, the best buildings that we're in, we have some buildings that we have 90 plus percent market share. That is not normal. And those are buildings where the tenants tend to be the most levered to bandwidth and, therefore, are more interested in Cogent's products. I think what hurt Cogent's Corporate business is three factors. One, very obvious increase in vacancy rate. That's easy to understand. There's just less people to sell to in the building. Two, many customers basically stopped making changes because of the uncertainty of COVID and the uncertainty around work from home versus return to office. And I think that picture is still not perfectly clear to every company, but it's increasingly coming into focus and things are improving. And that improvement and clarity is allowing customers to now place orders, and it's helped us improve our Corporate growth rate. And the third factor is, we had a sales force that was remote. And while we tried as hard as we could to make them as productive as they could be when they work from home, because of our high turnover in a direct sales position that's telemarketed, we saw a decline in rep productivity. Now that we brought reps back to the office, our trainers are there in-person, we have seen rep productivity improve and rep turnover decline. Again, we can't predict the pandemic, but we sincerely hope that, with the vaccine policy that we've implemented, that we'll not ever be forced to send our people home again. I think this was a once-in-a-lifetime event, maybe hopefully once in hundreds of years. And as a result of that, all three of these factors, I think will help us improve our productivity. Now to your second question about Wi-Fi networks, DAS networks and small cell, we have worked very limitedly with some wireless carriers to provide all three of those different solutions. In the vast majority of our buildings, we have the right to do that. There are a small percentage of our buildings where we would have to go back to the landlord to get an additional right. But that would not significantly impact our ability to participate in this segment. So far, all three of these technologies, I would say, are limited in how widely they're being deployed. So the answer is yes, it's an opportunity. Yes, we're talking to the right players. But today, it's not a meaningful contributor to our revenues.
