As my server is gone down suddenly and I don't have a chance to find out what is with it, I decided to move my blog to cloud platform.
I chose Selectel as hosting provider. Prices start from 50 roubles (about $1.85), this is only for keeping virtual machine for month, without running it. For my blog traffic (almost 0 :) ) overall price will be about 70 roubles (about $2.60) per month, it's very cheap I think.
UPD: After month usage, actual price is about 44 roubles (about $1.57).
