Arbor Networks: Security to the Core

While Google’s YouTube outage today generated a steady stream of tweets and blog posts, a quick look at traffic across 50 or so small / mid-size ISPs around the world suggests this was more of a “blip” than a global outage.

Certainly the outage was nowhere as large nor prolonged as the great “GoogleLapse” last year.

Below is a graph of traffic originating in Google (AS 15169) over the last 24 hours using data from 50 ISPs around the world selected at random. All times are EDT. Looks like a small outage overnight preceded the larger traffic 8am EDT drop-off.

And a quick aside, my intent is not to pick on Google (unless, of course, they do not pick Ann Arbor) — all providers have outages. I just find Google an especially interesting case study given their size and overall impact on the Internet.
