This might be due to the fact that more companies are buying backup
connections and announcing maybe only a /24 or /23. Of course, Verio will
filter them saying it is good for the net. Tho they forget that they send out
what they claim to filter. Seems they might have another motive for
filtering...

Our routers carry 1.1 million paths + in their tables today. I have seen
higher numbers (that was the first router I logged into). Current GSRs and
Juunipers in the core should have no problems with 100,000 routes.
