Brief Network Outage
It appears that shortly before 7pm some where upstream from St Louis AT&T Internet had a total network outage that lasted a few minutes with misc routing problems that lasted at least 30 minutes more.
Both the semo.net & IMS AT&T Internet connections lost all INTERNET traffic PAST St Louis for around 5 minutes. We experienced routing problems to the Socket COLO which feeds all of our dial up service for SBC/AT&T areas for another 10 to 15 minutes and to the Level 3 COLO that feeds our Windstream DSL and some Windstream dial up for a total of around 30 minutes.
While the specifics of the problem have not yet been explained by AT&T, the problem does appear to be resolved; thank you for your patience.
