BGP leak caused Internet Outages in Japan

Some news for those who route in the AS stratosphere, rather than just in lowly IPv4/6 prefixes

Wow...

Any chance that an outsider could have done that, or would that condition have to originate from inside Google?

My best best is either:

A) Mistake

B) Mistake

C) Mistake

Holy crap. My old job must have had a rough day. They were almost entirely on Windstream (7029) :S

Interesting read! Someone must have had a very bad day at Google!

Here's the Internet Society's commentary. The message is don't trust anyone, look after your own defenses (like, don't just rely on others to block advertising their RFC1918 IPv4 prefixes, you should prevent any such prefixes being allowed into your network). Google claims it was fixed in 8 minutes, but too late she cried!

Jimmy Ray Purser (formerly of Cisco Techwise TV) explained it well on FB.
When asked "So who peed on what?" He repied-
"Google peed in a glass that Verizon took a drink of then Verizon puked all over the rest of the party guest, which total killed the party vibe for a while"

eaadams is right. It is 100% laziness on verizon's part. They should be blocking and only allowing google's prefixes. What a shame.

Great article, eaadams. Good BGP practices are like vaccines, if enough people do them, you can get some herd immunity from the dorks that don't do them.
