The same folks who are working like demons on the epic masterpiece that is NationStates2 have now taken over the hosting and general maintenance of NS. Although the current forums are still hosted in Jolt (we're working on that as well), you should find the site a lot faster as we've migrated it to very beefy servers in our data centre (in New York City, if you're interested).
To cover a little of the monthly server cost (these are not cheap at all!) and make sure that we've got extra resources for general NS development, we're going to put a very small piece of advertising in the left-hand panel of the game. We promise it won't be intrusive and it helps make the game better for everyone :)
