OK - Some more details. My good friend Doug Madory notied drop of Tata Comm AS6453 transit by Vodafone (twitter discussion here https://twitter.com/DougMadory/status/1293963035216945153). So I traced one of Vodafone India IP - 188.8.131.52 via all Indian RIPE Atlas probes and found this:
Jio -> Vodafone is from outside of India:

I also checked NIXI route servers to see if Vodafone AS55410 routes are visible and saw quite low number of routes from AS55410. Strange case. Airtel seems to be dropping traffic as well as per RIPE Atlas traces.
from their looking glass saw:
Chennai: AS path: 174 9583 55644 55410 38266 ? (Originator)
Delhi: AS path: 3491 1273 55410 38266 I (Originator)
So Vodafone India lost connectivity to virtually all networks in India inside India and routing from outside of India. Unsure why.
Anyone got any replies from Vodafone on direct tickets?

I heard both Tata Comm and Vodafone were missing many of their routes besides NIXI route server. Though I cannot verify that. I checked routes of Vodafone AS55410 announced outside of India mostly behind Vodafone/C&W AS1273 and those announcements seem consistent.
Wondering if the issues you faced were with domestic Indian connectivity only?

Anyone heard about Vodafone AS55410 routing issues today? I hear many key backbones were missing their routes. Anyone else also facing this issue?
