Default DDoS
I believe I am under DDoS attack. My server just keeps loading and loading then when it doesn't load, it says "The Connection has been Reset". So am I undergoing an attack? My server load is only like .08 so IDK why I would be. If I reset the server, the site loads for a few minutes and then back down... Any advice at all?

Have you asked your host?

What kind of hosting environment are you using? Also, what are the results of the top command when it has problems?

I'm running a VPS with Plesk OS.

What did you mean by top command?

Type the top command in SSH after you log in and paste the results here, it may or may not show a problem.

Doesn't show anything out of the ordinary. What was your hosts' answer?

They think the CPU is shot, due to the fact, that my load average is now 0.0. I mean look at the log above, the CPU doesn't even show to be working.

CPUs rarely break down. Is this problem occurring on other VPSs on the same machine?
