@it_neber_ekered There are known cable breaks impacting a lot of Kenyan ISPs right now, but "weird" is subjective :)

CN@it_neber_ekered·
@bgptools are you seeing anything weird with bgp.tools/as/15399? I'm not too familiar with troubleshooting BGP yet to find anything but something is up. Thanks!

@DougMadory Yeah ROV won't prevent this. But it gave a route for ROV invalids to go via Airtel/TI and hit their destinations, If you did this enough, and the other carriers accepted all 8 /3's, then ROV would basically be moot. That would be a exceptionally stupid situation though!

Surprised by the comments along the lines of, why didn't RPKI ROV stop this? First of all, there is no ROA for this address range so ROV can't do much here. rpki-validator.ripe.net/ui/96.0.0.0%2F… Also, this is a less-specific route, so, in theory, it shouldn't affect much Internet traffic.

Looks like AS9498 (Bharti Airtel) typod a /32, /31 or /30. And turned it into a /3 (aka, 12.5% of the IPv4 internet) and other carriers (At least TI & GTT) accepted it!

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/s…

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

This halfed the number of RPKI ROV Validating ASNs according to bgp.tools (via RIPE Atlas) because those networks accepted the /3 and one of the probe IPs is inside 96.0.0.0/3

@acontios_net More than just TI and GTT, TI accepted it, and NTT/Cogent/Orange/GTT accepted it from TI.

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)

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)

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)
