[outages] CenturyLink peering issues?

[Stephen Flynn]

Just attempted a prepend (x4) on my Level3 advertisements --- only noticed a change within the NTT network tables.
Other large carriers received no advertisement changes (Telia, Hurricane Electric, AT&T)

I then noticed that my BGP session was constantly flapping.  I've now shutdown my circuit again.  Level3 is still announcing my address space.
Thank you Level3!

I brought my session back up, not accepting any routes, and prepending ours (just in case the change propagated)... it took a while, but eventually I do see the prepended routes.

But for a provider that said they shut down their link to Level3, I still see their routes... possibly (slowly) propagating changes but not actual withdraws?
