There has been issues around the same time every week but none which affect all users at the same time. They seem to be localised.
I have experienced issues over some of the previous weekends, but none this last weekend.
All the while, by the way, the server is 100% up and online (we get automated phone calls and Slack messages when that isn't the case).
We'll talk to see if there's anything we could or should change here, including logging a ticket with CloudFlare.
