From 8 cores to 36 cores processing power, let's see how the new database server holds up. Hopefully everything will be much faster from now on, but it should also give me a bit more room to scale horizontally.
@Gargron nice, works like a charm! Question: is instance-moving switched off for this instance because of the server troubles? I can't migrate, this server says “xyz is not an alias of this account” although I have done that and checked and re-done it several times.
