Hostgator shutting down my VM site

[BrokenChaos]

Hostgator for the second time has shut down my standard install of VM.
Its nothing special and I get average amount of visitors.

I get no prior warning... They just shut me down.
Something to do with to many query requests.

However, each time I get shut down, it seems to coincide with some urgent repair work that Hostgator is doing.

So, is it poorly written VM or Hostgator?

Is anyone else having issues like this?
