Many providers today, including so-called Tier-1's, have 
major issues with their RPSL infrastructure. We've had to 
bang them many times to manually accept our routes because 
their route server implementation that pulls from all 
reputable sources is simply broken.

Much pain has been seen over this.

RPKI is a solution, but that's an entirely different 
discussion :-).

I don't think this is something we should get comfortable 
about.
