Any idea how often Cogent, XO, and Level 3 update their prefix filters from the IRRDBs?

Maybe not. My client's upstream just said they released the prefix to their upstreams. They had previously referenced IRRs.

I got a recent answer from Cogent support stating they don't use IRR (at
least for their customers).

Hello,

Seabone/LANautilus/TI Sparkle (AS6762), an italian Tier-1 with strong
footprint in Latin America updates it once a day at 06:00 AM at Milan time.
If I recall correctly, only during business days. Works like a charm.

Best regards,

Kurt Kraut

Back when I had Level3 circuits, they updated at midnight Mountain time. I don't know if that's still the case, especially now that CenturyLink has gobbled them up ...
