To all,
Comcast engineers have been working around the clock to investigate the root causes of the recent DNS outages and after further investigation, the cause has been tracked down to a memory leak in the software system that our DNS system uses. The appropriate measures have been taken to correct this issue and the fix has now been in place overnight with no negative effects on the DNS system. At this time, we are confident that this memory-leak fix has resolved the DNS issues and we will continue monitoring the system closely to ensure the performance remains at peak performance.
In order to address some of the more popular topics that have appeared during the past week, in regards to crediting for lost service during this time, the policy of handling credits is based upon each local market's discretion. Thus, you will need to contact Comcast Customer Service in order to receive any credits for lost service.
In regards to providing details of these outages to the customer, we are still deciding on a final way to notify all customers about these outages. We have provided all of the details of this outage through these help forums and all other avenues of support. However, we are also investigating options for providing information about the outage and crediting procedures to all customers.
In conclusion, Comcast does sincerely apologize for any inconveniences these outages may have caused each of our customers and we do appreciate your patience while we have worked to resolve the issue. We will be using some of the findings about our system that were obtained during these outages to help improve the overall operations of our system - from customer support, to messaging information to the customer, and also to the network itself.
Thanks to everyone in here for helping out!
Jason
