There has been a lot of post about best VPS hosts and so on. Lets change the topic and post your worst VPS hosts .
I was only with 1 VPS provider "Adiungo" and after 2 months the results are bellow:
50% loss of traffic
CPU load: almost every hour you see red mark in front of it I swear!
Lost position in Serp!
but good support.
I made a mistake that payed annualy. maybe next month I move to another server and won't even ask for refund!
