Super slow droplet
A few weeks ago I setup a 2nd droplet on SFO1. I never had any slowness issues with the first SFO1 droplet, but this new one seems to go through hours-long periods of slowness (e.g. 20 seconds to load a small static web page). If I check my other SF01 droplet at the same time, it's normal/fast loading.
On the DigitalOcean control panel, the new droplet shows close to zero resources/cpu being used. I have an iptables firewall in place, and access to the new site is limited to myself.
In the 3 weeks that I've had the new droplet, this has happened 3 times that I'm aware of.
Installed on the droplet is Debian, Apache, PHP, and MariaDB.
Any ideas? Things to check?
