The site suddenly went into read-only mode today at ~13:25Z came without warning. The banner that goes along with read-only mode says:
This site is currently in read-only mode; we’ll return with full functionality soon. Follow @StackStatus or visit our status blog for more info.
Except, by 13:43Z, there had been no tweets from @StackStatus since November, and no posts on the status blog in three months. (Yes, I know it says "2 months ago". It's lying. The last post was written on 8th September.) So there was no explanation, either.
By now even the read-only site was gone, only a single line of default-font text reading:
Stack Exchange is currently offline, we'll be back shortly!
When's "shortly"?
Now, I appreciate that the team was likely busily trying to fix the fault — a tweet eventually surfaced at around 13:45Z claiming "database issues" — but could you perhaps do a better job of keeping us informed about maintenance, faults and the like?
At the very least, if there are no recent tweets or blog updates, the read-only banner shouldn't send us to Twitter or the blog for more information.
