AT&T snafu hits access to Microsoft Web services

An Internet routing error by AT&T Corp. effectively shut off access from around 40 percent of the Internet to several major Microsoft Web sites and services on Thursday, Microsoft has said.

Access to Microsoft's Hotmail, Messenger and Passport services as well as some other MSN services was cut for more than an hour after AT&T made routing changes on its backbone. The changes were made in preparation for the addition of capacity between AT&T and Microsoft that is meant to improve access to the services hit by the outage, said Adam Sohn, a spokesman for Microsoft.

"We are doing some work with AT&T to add more capacity and better route traffic between AT&T's network and Microsoft's services," he said. "AT&T made some changes in preparation for this and the effect was that traffic was incorrectly directed causing some of our services to become unavailable to 40 percent of Internet users at peak."

"Microsoft services were up and running but people could not get to them," he said.

Thursday's outage ran from 1:15 p.m. PST to 2:30 p.m. PST (21:15 to 22:30 GMT) although problems might have lingered for some users, said Sohn.

The problem is unrelated to an outage on Monday this week that left most of MSN Messenger's 75 million [m] users unable to access the service for around five hours, said Sohn. "We had not started the work with AT&T on Monday."

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.

MSI GS65 Stealth Thin

If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.
