Their service is simply amazing. I've had a few VPS from them for over seven months, and issues rarely happen; whenever they do, they are addressed in minutes instead of hours like many other providers.
Also, RamNode is pretty much the only provider where I haven't had any problems with the processor. I'm mostly running some light game servers that don't use much memory / CPU but do need consistently available CPU or else the games will "spike". I've had problems with several other hosts (only reason I use them is because RamNode only has locations in Atlanta :( ), but never with RamNode. Similarly, operations like upgrading packages take only seconds to carry out.
In fact, the only other VPS I had that had the same quality as the 512 MB SVZ plan from RamNode were trials from Zunicore... which costs something like $50 monthly compared to $4.88 monthly. Going to try out BuyVM though.
Consistent 16 MB/s download is also nice.
Thanks for the great service!
