Net boffins brew poison for BGP hijacks

The Border Gateway Protocol (BGP) is one of the Internet's basic pieces of plumbing technologies, but it's also so old it was designed before the security needs of a multi-billion-user network were understood. In particular, BGP is notorious for allowing sysadmins to “black-hole” huge swathes of traffic either by fat-fingering …

Cisco borked its own BGP code in IOS XE, has since patched

Cisco's pushed a fix for a border gateway protocol (BGP) denial-of-service bug in its IOS XE operating system.

Internet boffins take aim at BGP route leaks

One of the most persistent bugs in internet infrastructure, route leaks in the border gateway protocol (BGP), is in the sights of a group of 'net boffins with their new Internet-Draft.

Fat-thumbed a BGP entry? Relax, now your pain has a name

Users are familiar with those occasional events in which a sysadmin fat-thumb results in traffic getting deep-sixed – like, for example, this week's huge Telia outage.

Google cloud outage caused by failure that saw admins run it manually ... and fail

A mistaken peering advertisement from a European network took Google Cloud's europe-west1 region offline last week for around 70 minutes. The slip-up happened when an unnamed network owner connected a new peering link to Google, and in the process, it advertised reachability for far more traffic than it could handle. As a …

Russian internet traffic detours through China's Frankfurt outpost

Russian domestic internet traffic has in the past year sailed through Shanghai due to routing errors by China Telecom, network boffin Doug Madory says.
