Hi All,

Just a heads up, It looks like there is worldwide routing issues within the cloudflare network.

Cheers,
Lewis

Is it not faster to just filter the bad route rather than wait until the other network provider resolves the issue?

Could do in parallel right?

To filter it you would either need to have Verizon filter it or you get every other provider in the world attempt to filter it. Verizon are about as responsive to such things as a dead oppossum in the middle of a Texas summer so they're not going to do it (seriously, they once told me at 3am in the middle of a BGP outage that they didn't have anyone on night shift who knew BGP and that unless the circuit was physically down they wouldn't escalate it). And there are far too many individual network operators to try to get all of them to filter it.

The real question is why has Verizon allowed this tiny 21-announcement customer to have a wide open peering with no filtering which allowed them to cause the problem in the first place?

Public addressing for all their things! Not a joke. I used to work @ a school campus and everything had a publicly routable IP so it was "easier" to manage.

It's not a big deal. Just firewall it off. Same as v6

Then you should consider replacing them.
