[Outages-discussion] [outages] Optus/Akamai

[DaZZa]

(moved to discussion)

With Optus? Anything is possible. This is the company that leaked
personal information on 3.5m people less than 18 months ago with a
ridiculously badly secured public API.

I have my doubts that it was completely related to BGP - especially
since my wholesale/enterprise link was fine, and still advertising our
ASN prefixes to the world (I checked on multiple looking glass sites
located in other countries) with the appropriate paths being active -
I suspect the BGP drops noticed by various people were due to some
major component of their core failing somehow.

I suspect we'll never know for sure. Optus are notorious for not
releasing public RFO's for outages of this type - and since my link
wasn't affected, I can't even get on my "I'm a customer, I demand to
know!'' high horse and get one.
