It's not a load problem though, it's because some loser is DDoSing the server. Doesn't hurt to move to other instances where it isn't happening but the real solution would be to find who's doing this so they can be brought to justice (or silenced from the internet forever, whichever is easier).

Please tell others to stop misrepresenting this issue, it is an attack, not a user overload problem and nobody who's misrepresenting it that way is doing anyone any favors except the attackers by presenting it as such. Instead it should be presented as what it is.
