Geoff's data at Potaroo had the FIB clearing 1M back in Febuary if memory serves. So this already happened months ago.
I'm confused by that. I show 990450 prefixes in my FIB, 990478 in RIB. Potaroo shows 1022758 prefixes in FIB for today. Why would there be a discrepancy of over 32k prefixes? We're blocking exactly 0 prefixes from our three upstreams. I would understand a hand-waving explanation of "this is the Internet, it's always being updated, and everyone has a different view of it" if the discrepancy were 10^2 or even 10^3. But over 10^5? That's a bit like the three top ASNs for route count just disappeared from the Internet. -Brian
