DevFeed: [Airtel-Tata Comm routing is cold potato in India?]() Original publisher: [Read original article]() Published: 2026-05-20T13:20:53Z Content type: opinion Language: en Sources: [Personal blog of Anurag Bhatia]() Topics: [Routing (disambiguation)](), [networking](), [BGP]() Tags: [airtel](), [arelion](), [as1299](), [as174](), [as4755](), [as9498](), [bgp](), [cogent](), [india](), [routing](), [tata-comm]() ### AI overview An analysis of traceroutes between Airtel (AS9498) and Tata Comm (AS4755) in India suggests their routing tends toward cold-potato behavior. The article explains hot- and cold-potato routing, compares Arelion and Cogent traces, and examines possible interpretations of an Airtel-to-Tata Comm trace. ### Source excerpt Over the years, I have seen a number of traces between Airtel (AS9498) and Tata Comm (AS4755) in India, which strongly suggests that routing tends to be 'cold potato' between them. By default, routing between large backbones that interconnect across different locations is typically 'hot potato' - meaning traffic exits to other ASNs as close to the source as possible Hot potato routing is common Hot potato routing is quite common across large backbones. Let's analyse this concept by tracing between Arelion AS1299 and Cogent AS174 from their respective looking glasses.

Traceroutes and public BGP route data indicate traffic was taking an indirect path through the United States, while later updates report improved routing and restored connectivity after a MENA cable repair. ### Source excerpt Since 20:08 IST / 14:38 GMT on 28 Jan 2026, the latency between Airtel India and Europe has gone up along with significant packet loss.
