On June 27:th, the https certificate for lemmy.today was supposed to renew itself. Its set up to automatically renew every 3 months, and its been working perfectly since the site was started over 2 years ago.

But this time it failed to do so, due to a syntax error in the web server config that was not noticed until this incident took place.

Its been fixed now but took more than a day unfortunantly. Sincere apologies for the long delay - it was because I was on vacation in Madeira and in the process of travelling home that day.

Life finds a way to kick us in the balls sometimes.

I was worried, so I checked the error. And it made me confident something had gone wrong with autorenewal.

Given that my job had a days-long partial outage due to CLOCK SKEW between nodes, a cert renewal issue is positively understandable.

Glad you were able to get it sorted out, but hope you have some more vacation to get back to!

Oh man, clock skew between servers totally screwed me about two years ago because the servers were load balanced traffic and applied their server timestamp to realtime data - which in some cases led to entries being out of order. (never mind all the other issues with this implementation)
