Saying something like...

"Admins, thanks for getting everything up and running again - next time this happens, could you guys post a Tweet or something? "
might've been more effective than saying things like...

"The down times are annoying. Especially as there have been more & more of them in the last year. People come here every day & they get used to the site being up & expect that.

...why did it take 10 hours for any admin or mod to even acknowledge there was a problem?

This site seems so fragile now...

...it looks to the outside like you're either ignoring the problem or that you don't care.

Does most of this suck? Yeah. But that's the admin job."
