Comcast Nationwide Outage caused by Level 3

Comcast Has A Nationwide Internet Outage – November 6th, 2017

Apparently, the Internet outage that caused users from as widespread as Boston, Birmingham, Spokane and Seattle – in other words, the entire country, was caused by a router configuration error by one of Comcast’s backbone carriers Level 3. Comcast, of course, has made no (or little) comment about this significant outage. Interestingly RCN, who was also impacted, quickly re-routed their traffic over another backbone to minimize the outage to their customers – one wonders why Comcast was not able to do so as well.

Outages such as this demonstrate how important it can be to have a backup Internet provider for your business, which can reduce your downtime in the case that one of the providers has an issue.
