A Border Gateway Protocol (BGP) routing incident saw a bunch of high-profile Internet destinations mis-routed through Russia on Tuesday, US time.

In what BGPMon called a “suspicious” event, “Starting at 04:43 (UTC) 80 prefixes normally announced by organisations such Google, Apple, Facebook, Microsoft, Twitch, NTT Communications and Riot Games were now detected in the global BGP routing tables with an Origin AS of 39523 (DV-LINK-AS), out of Russia.”

The glitch happened twice, the monitoring organisation reported: Once between 04:43 and 04:46 UTC on December 12, and then between 07:07 and 07:10.

BGPMon said in spite of the brevity of the events, they matter because the announcements were “picked up by a large number of peers and because of several new more specific prefixes that are not normally seen on the Internet.”

Peers that accepted the announcements and made them reachable included Hurricane Electric and Zayo in the US, Scandinavian international collaboration Nordunet, and Telstra in Australia.

The autonomous system (AS) that made the announcements had been largely dormant for years.
