Hey Mozheads, Brad here! It's a beautiful Friday here in Seattle, and I hope the day finds you well wherever you are.

We've got a May Mozscape index for you to check out! As always, the new data can be seen on Open Site Explorer, the Mozbar, your PRO campaigns, and the Mozscape API.

This is a very special release, you guys. This is the first Mozscape index that was processed by our virtual private cloud in Virginia! This is a big part of our long-term strategy to streamline our processing for maximum freshness and value. For now, some of our indexes will be from our Elastic Compute Cloud clusters and some will be from our VPC in Virginia while we figure out how best to use our resources.

Our histogram shows that the index was crawled from the second half of March through the first half of April.
