Hi David,

I'm sorry you've had so many poor experiences with Level 3 recently, but I assure you that we have acknowledged the problem and are actively working on it at present.

Of general operations interest,

I just saw an event notification that matches the description of the problem and our NOC, engineering team and vendor are working together to solve the problem.  If you are a customer and believe you are impacted, you can reference event case ID: 6237890 as potentially being the related case.

It is not just you.  We are seeing issue with that Level3 router/site as well.

I would report it to Level3, but I don't see any need to add to my already extensive collection of one line Level3 support responses saying "All is well.  Nothing to see here.  All is well."

My guess would be that your up/down for individual IPs is a result of your testing methodology. That Level3 router/site appears to be dropping some packets to all IPs that I tested before dropping my conn there.

Our response to the nearly constant Level3 issues of the past 12/18 months has been terminate them.  The washington1.level3 site was unfortunately the last on my list of DCs.
