Both issues you’re describing are actually one and the same issue.
There was a problem receiving status updates from the hosting platform. This issue lasted roughly from the 29th of August around 14:00 until the 31st of August around 21:00 UTC.
The members area has pretty decent recovery mechanisms in place, which is why your account did become was marked as active after those 32 minutes.
However, there was no recovery mechanism to load the database hostname for your account. And since the database hostname is necessary to construct the phpMyAdmin login URL, that option is currently not available.
A background process is now running to retrieve the database hostnames for all accounts for which the notification was lost. This will take a few more hours to complete. When it’s done, all affected accounts will be able to access phpMyAdmin again from the members area.
