Are you running routed? If you don't need to, try disabling it; this will insulate your servers from being taken down when the router goes on the fritz. Routed removes any default routes, so if your net route gets busted by a fried router, your computer can't figure out how to talk to the rest of the world. Don't forget to add a default route if you haven't been running one. One of the UOs routers killed my box in my first year here with the same type of problem; routed died a quick and painless death.
