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 think a static page page explaining to users that the server is being upgraded would be best.
Beehaw.org did this, their nginx seems configured to return a nice error message.
Exactly. That’s what I meant by a 502. Like most HTTP responses, you can associate a template with it and it’s even recommended when you have a lot of people using your service and you want to explain why it’s not accessible right now.
