Yes...about the same time here...maybe a few minutes later.  I was seeing 
traces stopping at ae-63-63.ebr3.Atlanta2.Level3.net.  Things seem to be 
moving again.  I just unshut our L3 BGP session.  Interestingly, while 
Level3 was having problems, our local Akamai cluster was apparently not 
working properly.  images.apple.com resolves to our local Akamai cluster, 
but requests there were timing out.
