While I agree that TM needs to look into its operational procedures, I
think Level(3) needs to shoulder more of the blame, and not simply pass
the buck to TM.

TM has several more upstreams other than Level(3). Assuming their issue
affected all their border routers, we did not see an issue via their
other upstreams other than Level(3) - although this is conjecture on my
part.

Level(3) should have filtered at the time they were turning up TM.
Simple as that.

We all know we should never trust customers. So...
