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.

I am not sure if PostgreSQL locks everything when you dump it. If it does, that could lead to issues if you are currently making database transactions. If you have questions regarding downtime, you can look at the status page and/or contact support with questions. Looking at my statuses of my droplets (All in NYC3), I had 100% uptime for the 23rd. You could’ve experienced a routing issue, etc. There are many causes for downtime, but the first place to check are your logs.
