Hi, Andy —

Are you failing to advertise it, or are they filtering it on ingress, or are they failing to send it to their other 
peers?

One configuration mishap which is starting to come along more and more partial or poor reachability caused by route 
objects which are not correctly published in the IRRDB. It is going to be essential to make sure that you have properly 
recorded IRR route objects in, for instance, RADB.  More BGP speakers properly filter their peers using information 
that is published there.  Avoid future reachability problems by checking this today!

Yours,
A friendly route-server operator with strict filtering
