If that happens, you can contact me personally:
http://liraz.org/?ContactLirazFWIW, I'll probably already be on top of it as I've implemented robust Nagios monitoring that triggers SMS notifications to my phone when anything goes wrong. If the site goes down for 5 minutes or the blockchain stops updating for more than 2 hours my phone will be lighting up.
Also, I've put in quite a bit of effort to make sure the next downtime we have will be due to hardware failure rather than a software or operating system issue. All the site's key services are monitored by systemd and set to restart automatically if they leak too much memory or go down.
I just checked and it's working, i tried i think last week and didn't work.
Thank you for notifying us liraz, where should we report when it happens again?
