dreadful too many connections message

so finally my site was seeing the dreadful message 'too many connections' and appears that the site was down when I was checking at 2 am early morning

well I was awake because it is week-end and friday morning and so can sleep till afternoon and normally watch a movie late night thursday actually I bought 'rang de basanti' VCD but tuned it to ONE tv and happend to see tha 'father of bride 1' comdey movie and then was hooked to that 

so this too many connections was a problem from the host so contacted them and now it is fixed I was wondering may be since I upgraded my drupal may be it could have caused the problem but anyways things are okay now.

hope not to see again that dreadful message but again things are not in my hands and I cant do anything to the php.ini or change configuration settings.
