Dan Todd, chief technologist for public services at Keynote, said Microsoft had apparently solved Wednesday night the problem that rendered Microsoft sites largely inaccessible for nearly 24 hours. But similar troubles started building again this morning. Late Tuesday and Wednesday, most of Microsoft's websites could not be reached by users because of problems with its domain name servers. Domain name servers are used to route Internet users to the appropriate website when they enter an address in their browser. This morning, Microsoft spokesman Adam Sohn said the problem was caused by a router that was reconfigured late Tuesday.
Routers control the traffic between the internal network and the outside world.
And rarely are the errors caused by domain name servers. Michelle Rushlo is a reporter at UpsideToday covering big-cap hardware and software companies. Network and research Internet industry deals and dealmakers. 1993-2000 Upside Media Inc. All rights reserved.
