Yep, easily .. we saw big routing problems for that /19 and a lot 
of innocent bystanders, in two waves, correlated across most sources.  

First signs of trouble at 23:12 GMT.  Then long periods of unreachability, 
from roughly 23:15-23:42 GMT and 01:26-02:10 GMT (the second one less 
well-correlated; routes were still available from some of our peers). 
Routes were fully restored globally by 02:12 GMT, presumably after the 
upstream rate limiting kicked in. 

If anyone has mrtg plots for the affected links, I'd sure like to see 'em.
