accessing forum problem

[mayanks]

Hi guys,

i recently changed my host and then i am facing a problem that most of the members on my board are not able to access my website...
I've got a high traffic site (I guess...10k+ daily) and noticed that in the past few days my hits have gone down quite a bit. Recently I've been receiving emails from people saying that they haven't been able to access my site.

all stats are going down i.e members registrations, members visits etc etc

host says everything is fine from their end and the problem is of local isp..

i am really pissed off and dont know what to do...

FYI info my website is www.badhackerz.com

Please let me know if it is opening for you guys

Thanks
Mayank S

Your MySQL server is overloaded. If you are on a dedicated server which I am assuming you are go to vbulletin.com and post in the server forum for a server optimization.

If you are on shared its time to switch hosts again this one is overloaded on mysql.

Have a look at the manual's page.

Did the DNS change already propagate to all your members?

What is the IP address of your new server, if i do a ping of yur domain i get the IP 208.43.162.218. Your site is not opening for me.
