Now, I can’t go to my site.
It’s always display " Cannot Find Server ".
Some of my friends can enter to the site but some people can’t.
I tried to use a proxy and I saw my site perfectly.
So that did DreamHost banned my IP ?
It sounds like you cannot resolve the hostname. Did you just update the nameservers on your domain?
No. I checked the nameservers and it’s alright ( ns1.dreamhost.com, ns2.dreamhost.com, ns3.dreamhost.com. ). I mean that some IP address can enter the site but some IP can’t.
That is I can’t enter all the sites hosted by DreamHost ( included DreamHost.Com )
I rather doubt that dreamhost blocked your IP… Perhaps your ISP is blocking for some reason? Probably best to contact support and see if they have any ideas.
