About 50% of those who replied used RADB or another similar database (possibly their own, like CA*NET, MCI/CW, Level3 etc.) for filtering either peers or customers. However, I suspect this number is heavilly skewed in favour of vocal NANOG people who like IRRs. Filtering customers was way more prevalent than filtering peers. I said I'd repost the stuff anonymously, but some contributors often post here and thus may chose to answer your question on or off list. > Connectivity failures can and do result when RADB records are not > properly updated, which does happen from time to time.

Well if they could agree on a routing policy language, that would be a fine start. -- Alex Bligh GX Networks (formerly Xara Networks)
