So, I woke up to a bunch of customer service tickets. Essentially a repeating group on my site wasn’t loading and so users couldn’t see or book classes and thus were unable to join them.
This issue resolved itself as far as I can tell.
But I didn’t push any changes to live before/after this, there is nothing “odd” in capacity or server logs either.
All really weird, never experienced any issue before and seems to be resolved now but what could have caused what is a pretty major issue for my app?
Any ideas greatly appreciated.
