I'm monitoring the v6 version of www.twtelecom.com (2001:4870:800d:fe1::11) and saw it go down from 1:48 am (Central) to 4:25 am (Central), so essentially the same time.

I'm a TWT customer, and still not seeing the /32, but am seeing lots of more specific /48's from it. I thought this was interesting though: $ whois as4323@whois.arin.net [Querying whois.arin.net] [Redirected to rwhois.twtelecom.net:4321] [Querying rwhois.twtelecom.net] [rwhois.twtelecom.net] %rwhois V-1.5:003AB6:00 rwhois.twtelecom.net (rwhois_ngd v0.9.0 by James Sella) %error 230 No objects found ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________

I don't think I actually checked which prefix we were seeing when connectivity was restored at the time I posted my follow-up. Right now we are seeing two prefixes from TWTC: 2001:4870::/31 2620:81:8000::/48 (and also 2001:4870:E00B::/48 from a path transiting 4323) I don't know for sure whether they were advertising the /31 or /32 before the event this morning but regardless 2001:4870::/32 wasn't reachable in the DFZ (as itself or as a superprefix). bgp.he.net still shows them advertising a /32, so I suspect they only changed to a /31 very recently - potentially during or after this outage.

I hadn't looked for less specific, since the /32 was specifically mentioned. I am seeing the /31. ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________

My collector saw the /32 for "all year", and since today, only the /31 plus a single /48. The ARIN delegation records claim "it has always been allocated as a /31" (since 2005). gert -- USENET is *not* the non-clickable part of WWW! //www.muc.de/~gert/ Gert Doering - Munich, Germany gert@greenie.muc.de fax: +49-89-35655025 gert@net.informatik.tu-muenchen.de
It's possible that the TWTC's customer advertisements are different than their peering ones, no?
