[Solved] Website is frequently down

[xcrow]

I'm on Tommy plan, and I've noticed that the website is frequently down more than it should. At first I brushed it off since the plan does include some down time
but this is definitely a lot it happens every few minutes and it's making me start to wonder whether there's something wrong with my account specifically

What errors are you seeing?

Error 503 was a known problem on this server recently (should be resolved now), and 502 for a few minutes every 2 hours is normal (Apache restart).

It happens everyday once if not a few. I'm curious why Apache always give 5xx error

I've played around with "systemctl restart apache2". For my experience, it shouldn't take more than a few seconds. It really take a few minutes to complete in Johnny and Tommy? I'm just curious.

Yes, it does take that long in our case, because there's several thousand domains hosted on one server, which means a ton of Apache vhosts.

Johnny and Tommy each have about 5500 vhosts (a typical domain uses 2 vhosts, one for plain HTTP and one for HTTPS). Your typical VPS is probably going to have like 10-20 vhosts. An instance of apache on your home computer for localhost development likely has 1 or 2.
