Yeah I have heard crap about 1and1 many times but since they were dedicated boxes that we manage ourselves is was no biggy that the support sucks because we never use it. I can tell you 1and1 has some good servers, cheap, with lightning fast connnections. All means nothing if they can turn everything off in a minute with no warning though I guess.
It's not really a support issues as much as a fucked up policy on how they handle their DMCA email. I have used RackSpace which some consider the best support in the business but they fucked me over when it came to DMCA as well so it's not a simple fix nor as easy as saying it's just 1and1. Hosting companies often overreact to DMCA's and it's a constant problem with my clients since they sell stuff cheap and that's the manufacturers only way of going after them. Half the time DMCS's aren't even legit anyway, but scared companies freak out over them.
Bottom line is I need to look into offshore hosting I think.
