For those people who wandered here wondering why the teamspeak server is down, I'm currently upgrading my server. It should be back hopefully Wed 24 Nov 2010 around 10pm UTC.
I'd like a moment to thank the previous hoster, as they have provided a great service for me the last 1.5 years.
I would still recommend them if their packages suit your need : www.budgetdedicated.com
And for those interested, I'm moving to www.vibit.eu , using a "Vibit Light" server package.
