The only thing I noticed is that the instance seems to be doing something around 6am AEST each day and is unreachable for a couple of minutes. That doesn't seem to be what you're describing though.
This is more what I've experienced, but in the evening.
Confirmed. 3am (Perth time) Lemmy restart to negate the memory leaks. Not sure whether that's still needed after the software update a couple of months back.
Can turn it off and find out. I've done this a few times, each time I've ended up turning it back on.. I figure better brief downtime at a low usage time, than random downtime that may require intervention to resolve.
I've noticed that too, and I thought it was my potato phone. Haven't noticed it at any particular time though, for me it's just randomly happening.
I've also noticed this sort of thing happening roughly around 7pm
