Oh man I have laptop trouble myself so can hardly do anything here content-wise
As for site performance, now it's fine.
Also, we are still behind cloudflare's reverse proxies, and the under-attack-mode gets activated automatically when load becomes too high. Perhaps a bit too slowly.
I see it was on-off-on until about 2:00 CET, then all fine, then another period today from 18:00 to 22:00 where we had several load spikes and anti-bot kicked in, but since then ok.
I'm keeping an eye on things even though I'm unable to post or write much myself atm.
