Wasn't that it made me feel safe, but I do have to worry about my 
downstream customers who did exhibit the bug. As a provider, it falls 
within my goals to limit damage that might occur downstream in my 
customers' networks. Any time a bug in BGP that can be passed along 
rears its ugly head, I take notice and see what changes I might need to 
make to protect my downstream customers.

To date, I haven't seen any of them affect my routers. I have also 
looked into issues with dampening, as I don't generally dampen myself, 
but some of the downstream BGP routers can't handle the processor load 
when things become extremely unstable.
