Greg, the service problems we encountered today were due to a configuration
error with WorldCom's backbone routers that caused all requests to our DNS
servers to be re-routed.  Stuff never reached our DNS servers. This was a
Worldcom (MCI) misconfiguration much like the two episodes we had earlier in
this year.  Unfortunately, WorldNet cannot correct such mistakes as it affects
the entire internet backbone and must be done at the source of the trouble.
We expect an official statement soon.

Ok, but given this post you just made to another newsgroup, isn't it
reasonable to question what happened to the history of the previous
episode that should have enabled AT&T to fix this in less than 8 hours
THIS TIME? My question stands, waiting for the "official" announcement.
Why so long to fix it?

At approximately 8:15 AM [EST] on Wednesday, December 1, AT&T began
experiencing a series of service interruptions on its dial Internet Protocol
[IP] platform. The impact was nationwide in scope and affected AT&T's
Worldnet Service, Business IP Dial Service, and portions of its Virtual
Private Network service.  AT&T's IP backbone was not affected by this
incident, nor were there any service disruptions to customers using AT&T's
dedicated Internet access service.

Reports indicate that incorrect routing by another Internet Service Provider
[ISP] generated this problem. That routing error has been corrected, the
network has been stabilized, and service has been restored.

We apologize for any inconvenience these interruptions may have caused.
Thank you for using AT&T WorldNet Service.

This announcement is patronizing. It doesn't name the perpetrator (MCI)
who was identified on a newsgroup by an AT&T employee. It doesn't explain
why it took so long, when we were told this was what had happened before
(see below). It doesn't tell us what is being done to reduce the time
necessary to identify and repair future outages. It doesn't tell us what
AT&T is going to do to keep us as customers.

This is what we get for an eight hour outage?

I'm disappointed. And just last Saturday I posted a message praising AT&T.

An Apology... And an Explanation.

On December 1, 1999, there was an outage that affected AT&T WorldNet®
Service members.  First I would like to apologize for any inconvenience
this may have caused, and second, I'd like to explain what happened.

This problem was not caused by AT&T's network.  However, it did affect
our system, and our members.  Another Internet Service Provider made a
network change that caused the public Internet to have incorrect
information on how to reach AT&T WorldNet servers.  As a result AT&T
WorldNet customers could not browse the Internet and mail from other
Internet Service Providers to AT&T WorldNet members was delayed.  AT&T
engineers worked to isolate the problem and provided a work around to
restore service by 4:30 p.m.  In addition, AT&T notified the other
Internet Service Provider, who in turn corrected their configuration.
The smooth operation of the entire Internet depends on accurate
information and cooperation from all Internet Service Providers.  This
reflects the distributed nature of the Internet and its design

AT&T WorldNet Service continually works to improve its service.  In
fact, based on a recent study by Solomon Wolff Associates, AT&T WorldNet
Service was rated as having the highest level of customer satisfaction
among the five largest Internet Service Providers.

Again, you have our sincerest apologies for yesterday's outage.  Please
be assured that we are working to prevent this kind of an interruption
in the future.

Thank you for being an AT&T WorldNet Service customer.

Ed Chatlos AT&T WorldNet® Service Vice President & General Manager

The details of the software we use and how it works are considered
proprietary. Full disclosure of the root of the problem would entail
disclosing some of that information. As such, the best we can say is that
the problem was due to a software configuration issue.
