my applications were down but servers were running good
Hi, my current stack is on CentOS 6.4, NGINX with Passenger, Postgresql, Redis and Rails.
It has been happened today, during EST 1:22AM to 1:25AM, all of my server reported ping down, but I had active SSH sessions running from Putty. the failed ping also leads to my websites/application downtime for that 5 minutes.
Did Digitalocean had a network maintenance during the given period, on 23rd November? if not, how can I find out the exact reason about this?
My postgres server makes a dump every 2 hours, so it is not supposed to do any harm, otherwise I would have sites down every 2 hours always or frequently.
I need some detailed help on how to find out the issues, specially what logs to check or what status to check. Kindly help.
