Problem getting into any year Proseries

I am getting a "server busy" error on all years (versions) of Proseries. Never had this before.

Not having any other server issues at my office.

Id reboot the modem and any computers involved and see if anything changes....if youre still stuck in the mud, come back and we'll tag an Intuit engineer
