We’ll give the upgrade new try tomorrow. I’ve had some good input from admins of other instances, which are also gonna help troubleshoot during/after the upgrade.
Also there are newer RC versions with fixed issues.
Be aware that might we need to rollback again, posts posted between the upgrade and the rollback will be lost.
We see a huge rise in new user signups (duh… it’s July 1st) which also stresses the server. Let’s hope the improvements in 0.18.1 will also help with that.
I used to work with a guy who was a sysadmin for a moderately sized webhost in the mid-2000s when things like containers and cluster orchestrators didn’t exist and high availability/multi-master database systems were only really accessible to banks.
He once described patching the servers “like trying to change all the tires on a car without being allowed to pull over”.
