Airtel fixed the bogus announcement at 04:40 UTC today. Looking back at the bgp.tools data, Orange/GTT/NTT/Cogent also accepted the /3 via Sparkle (TI), from Airtel.
GTT's acceptance was down to a (now fixed) JunOS config gotcha x.com/packetsource/status/18…

Thanks BGP Ben for the alert! It turns out that prefix-length checking does contain some hidden man-traps

Partial de-peering between Cogent (AS174) and Tata (AS6453) yesterday, first reported by @bgptools.
Here's @kentikinc's view of the drop in traffic over 174_6453 beginning around 18:00 UTC on May 16.
(The previous TATA-Cogent Full depeering post was wrong)
It appears that TATA-Cogent have partially depeered in APAC. Cogent can't see APAC (notably India) routes anymore. It seems based on statements Cogent has initiated this depeering (Some EU/US routes seem to still be find)

Due to this Networks that are single homed behind AS6453 (in APAC) or AS174 will not be able to reach each other. This is similar but more serious to the previous regional NTT-Cogent depeerings (since the NTT ones "just" increased latency by routing via the US instead)

This seems to come off the back of Cogent trying to establish a market in APAC, and the main players in that region not wanting to have their market eaten away by Cogent (To be fair, Cogent is very good at getting prices down, and APAC is still quite expensive per mbps)

Has 2000::/12 been announced again?
Not yet!
But that did not stop GTT / AS3257 from carrying such a mistake

New bgp.tools feature: RPKI ROA History Search!
Allows you to search the RPKI ROA entries of the past, or to give you extra context of previous uses of a IP block. It was super useful when investigating the Orange Spain RPKI Incident blog.benjojo.co.uk/post/rpki…
