Here it trick for those who need to access to access paxum:
Open c:\windows\system32\drivers\etc\hosts (on linux is \etc\hosts) and add this line: 64.188.51.143
www.paxum.com paxum.com
Save it and then it will work like charm and it will always work no matter does dns work or not.
For future,to see on what ip adress is paxum hosted,use this site:
http://intodns.com/ and see what ip adress is on www record.This is important in case they will change ip adress,so you dont stack on old server in case you left this line in your hosts settings all the time.
