I switched to Razor Servers, unmanaged.. The deal was good, I saw pics of their new Dell servers arriving and them unboxing them, and it performs well. The caveats for me are they use WD Blue drives, which aren't enterprise level drives, and who knows what your host is really like until shit hits the fan. I don't imagine they have great support.
DC is in Philadelphia.
