At exactly 1 pm ET / 10 am PT, EmpowerDB was fully shut down for maintenance.
For the first half-hour all systems will be down. You may at points see a browser message telling you EmpowerDB doesn't exist at all. Then after that half hour you will see a message letting you know how much longer you should expect to wait until your site's is back online.
You may want to bookmark our Threads account. We will post regularly there to let you know how this maintenance is going.
