Hi Apoorv

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?

Thanks.

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 - 42.106.11.1 via all Indian RIPE Atlas probes and found this:

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?

Thanks.

Dear Anurag,

Our Noida customers are also reported same issue & as you mentioned, all the impacted Vodafone prefixes are learning from outside India.

We are still not received complaints from our Mumbai customers so suspecting that Vodafone have changed routing of specific location routes (North India) only.

We are coordinating with our upstream providers to get update from Vodafone Team.

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?

Thanks.

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?

Thanks.

Hello everyone

It seems to be improving. I re-run same check from all RIPE Atlas probes in India towards that Vodafone 4G IP:

https://atlas.ripe.net/measurements/26698719/#!probes

By looking at each of traceroute, we can probably say:

1. Tata Comm AS4755 - Vodafone India AS55410 seem connected again and routing locally now. 2. For Tata as well as it's downstream path is all now direct and from within India. 3. For Airtel and it's downstream path is: Airtel AS9498 > IDEA AS55644

Vodafone AS55410.

4. For Airtel and it's downstream route towards Vodafone has very high latency. It could be because of congestion or likely that traffic is still coming from outside of India, just that likely through IDEA AS55644 transit ports with AS9498 outside of India. While Indian operators except Tata do not put location in rDNS PTR records, I am guessing it based on my latency with hops before traffic hits IDEA AS55644.

Please do share if anyone gets an update from their respective transit providers.

Thanks.

Dear Anurag,

Our Noida customers are also reported same issue & as you mentioned, all the impacted Vodafone prefixes are learning from outside India.

We are still not received complaints from our Mumbai customers so suspecting that Vodafone have changed routing of specific location routes (North India) only.

We are coordinating with our upstream providers to get update from Vodafone Team.

Hi Anurag

Have asked my Downstream AS58590 who also has AS55410 as his upstream Peer to check with Vodafone on his direct tickets raised to Vodafone

I will update the same here once I get updates

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).
