Vmstat and iotop output please, 60 second polling rate is fine, 10 minutes worth during a time errors are prevalent. Pm me for email or send me a drive link.

Top if you get bored, although the other two ought to be sufficient

Most common cause is the server is just overloaded. That can happen for lots of reasons including too many people trying to access, server undersized to begin with, other scheduled workloads going on (like a backup running) which increases load. Fix can be approached in many ways including just moving to a bigger server, multiple servers with an up front load balancer, switching architecturally to a more fault tolerant configuration.

Basically, the system can be made as fast and as reliable as you can afford. Always a balancing act between maintaining a reasonable cost for the system and performance/reliability of the system.

and yes, I do this for a living - hold my beer........

Let’s go in together a build the ODT a DC!!! (With their money of course.)

A backup runs every night around 4:00 am and the site can go down for up to 20 minutes, based on the time you posted this that could be a factor. Aside from that the site has been performing great the last couple of days.


Do any of you use a VPN and use a country besides the US? We blocked many other countries over the weekend so it's possible that could have something to do with it.

No VPN here Okuma and same issues. US as well.
