Bill, you should contact their upstream and in the meantime, you could try to announce more specific routes, in order to reduce the impact. Of course, if the blocks are both /24, it’s not going to be very efficient as prefixes more specific than /24 will be probably filtered by your upstreams.

HI all,
Not sure where I should post this so trying here first.
Quick question, we changed hosts recently as the former host are moving their DC at the end of this month and our services would not work from their new location (wireless back haul).
We asked them to remove two of our IP blocks from their routers so they are no longer announced there as we have now got them announced at the new host.
Last Friday they confirmed by email they had done this, but it is clear they have not as reverse trace routes from some local (to London) sites show they are still announcing them even today.
This means many resources are unreachable by our clients and is causing significant disruption.
We have again chased them to resolve this.
Is there any mechanism in place or tools available to make it easy to either block this false route or have action taken against the provider for failing to stop it?
Thank you
