For a very brief moment today, users sending email to any @gmail.com address received this error:

"Your recipient address has been blocked by admins"

This was quickly resolved. It was the result of a deployment to standardize blocked recipients across the platform, though entirely unclear how *@gmail.com managed to land in the file as the deployment was merely a combination of what existed on the servers at the time, none of which should have contained this logic. We're blaming this on Murphy.
