If you’re wondering why half the internet broke tonight for a short period, TCS accidentally hijacked Cloudflare.HT @ssamulczyk

@GossiTheDog @ssamulczyk 1. TATA COMM and TCS are separate companies.
2. Cloudflare withdrew both 1.1.1.0/24 and 1.0.0.0/24 announcements due to an unknown reason. So its THEIR fault.

3. The BGP hijack you see is most likely due to a downstream customer of AS4755. Again the outage **isn't caused by TATA** it is caused by Cloudflare themselves.

4. TATA's Tier1 ASN AS6453 filters invalid ROAs but their domestic AS4755 doesn't.

@GossiTheDog @ssamulczyk Also take a look at that screenshot, "peers observed: 2%" the leak didn't propagate far.
