I'm not setting it on my router locally but sending it over to Cogent as 
a community string per page 22 of their user guide.

They use it to manipulate how traffic gets back to me so that is 
incoming from my routers view.

I also pad the AS  for the networks that I prefer to come back through 
the other ISP..

In the last 5 outages over the last few years, this has happened twice. I'm waiting on the RFO so I can further investigate why this happened. I think someone mentioned this in a post a few months ago too.
