Apologies for straying off topic,
Years ago several tools and sites were available for troubleshooting BGP
routing tables and viewing reachability over the Internet. I remember using
a site that, when you provided an ASN or IP address, you received a
tree-graph showing multi-hop peer points and latency statistics from dozens
of sources all over the internet. I know a lot of these sites went away
after the release of the vulnerability with the BGP's peering process was
disclosed. Some of the sites I bookmarked advertised that they would return
once a more secure way of offering this information was worked out. They
eventually just went away (example being http://nitrous.digex.net). Did
anything replace them? What are some of the tools and sites you use to test
if you network blocks are being seen where they should be?
Any suggestions would be greatly appreciated.

Look at http://www.bgp4.net/lg for web based looking glasses, and http://www.bgp4.net/rs for telnet based route servers.
Just if MD5 helps in anyway (except making the routers CPU load increase a lot 
The tool you mean is called NetLantis (http://www.netlantis.org/) but they are
not back, yet. Though I know, first hand, that the database is as-good-as done,
which was one of the bigger and latest steps. Thus maybe x-mas, but expect it
later, it will be back one day though.
