Microsoft Corp. said Friday that some people who use its Hotmail and MSN e-mail services are not receiving e-mail sent from Comcast Corp. accounts and other Internet service providers.

Brooke Richardson, a group product manager with Microsofts MSN online division, said the problem appears to be due to an increase in e-mail volumes, which it is attributed in part to the Sober Internet worm.

She said the high volumes are causing e-mail to either be delayed or not make it to MSN and Hotmail users at all.

Richardson said the problem began earlier this week. She would not name the other Internet service providers besides Comcast whose users were encountering the same problem. She also couldnt say when the problem would be fixed.

It shows how easily the introduction of a Worm into the system can cause havoc…that is assuming that it is the major contributor in this case.
Whatever way you look at it this is a timely reminder to ensure your systems security is up to date
