Thanks for the reply!
I'll answer as you wrote out;
a) Nope, I have never created my own nameserver entries with my domain name, the nameservers are all named with the provider such as ns1.mysuckyprovider.com
b) The nameserver entries have not changed so there is nothing that I can do to make changes to correct this. Not once was I informed that I need to change any nameservers either - not to mention I was not informed about the move....
c) I am absolutely positive that this is the case. Last night the site reverted back to the pre-move pages and again, everything was lost for a few hours. When I sent in (yet another!) ticket, I was told to "clear my cache in the browser" URGH
Yes, I am looking for a US based hosting company that will provide proper tech support when I call - and realize that I KNOW what I am talking about and not a newbie user!
I just want something that is reliable, responsive and can accomodate a move quickly and easily..... I have approx. 100,000 visitors per day so while I need a good deal of bandwidth, I don't need to be charged for oodles (heh! there's a techie term for ya!

) I need approx 25 GB of storage too.
Linux hosting is preferred as I'm not up to speed on Windows hosting (unless it's pre-year 2001).
Any suggestions or recommendations will be VERY appreciated and helpful!
Thanks so much!
Maggie
