It looks like not all servers are back online yet, so the issue should have resolved itself for some, but not all. I am continuing to monitor the situation, and don’t expect it to take much longer.
Edit: mostly back online now, but a little more to go.
Edit 2: the final servers have come back online, so that’s hopefully the last of it.
Edit 3: Those final servers have lost connectivity again. The data center has exceeded its estimated maintenance window, so they are likely dealing with residual problems. If you’re affected, please hold tight.
Edit 4: back online again
