Did the server had any recent ip change or maybe they are using the same hostname as their ip (e.g. server.domain.com).In that case the DNS change hasn't propagated to your machine yet. This takes 48-72 hours at most.
If not try tracing your server (monitor.sacnr or game-state) maybe the server has went down with you noticing.
