Performance issues due to forum backup?

Apologies if I'm polluting this place and the question has been brought up before and answered, but my search didn't turn up anything of relevance, so I'm asking. During the last two weeks I have severe performance and log-in issues every day during around 8.30 to 10.30 AM local time (CET+1, should be something like 2 AM PST). I'm assuming this is because some backup is going on somewhere (not necessarily on the forum itself) and would humbly inquire if someone knows something about it and if there is any betterment in sight. This has only occured recently, perhaps after some backend software has been updated and it really bugs me as I often start a reply only then to lose it due to the problems, having to type it again at a later point. I can also verify that it happens with different browsers and on two different connections, so I would rule out problems on my end and really blame it on the servers. If anyone has any info, I'd appreciate it.
