That is indeed one of the reasons why I'm seeking corroboration of the
pattern of behaviour; at least to isolate and eliminate any alternative
explanations. It would certainly be of operational interest (and certainly
not unknown in the annals of historical "stupidity") if, say, a single
fiber-cut or network upgrade was disrupting all of these different forms of
communication simultaneously. On the other hand, there's only a finite
number of imaginary backhoes you can conjure up before other explanations
begin to trump Hanlon's razor.
Right now, I think that http://bgpmon.net/blog/?p=450 explains (or at least
illustrates) why we were getting reports of widespread but not universal
Internet interruption. See also
I don't have a good explanation for the SMS problems, but lots of
independent reports; I've yet to have any real confirmation of no mobile
service, and lots of denials, so right now I'm going to assume that's
If anyone can get explanations from their peers in the region, please pass
them on (however incomplete or informal -- mail me directly if you'd rather
not contribute to rumors or non-operational NANOG discussions).
It's late at night in Egypt, and the biggest protests are planned for
tomorrow. A great deal of life-critical systems will be under a great deal
of stress during that time, and the interruptions in network connectivity
would be extremely worrying.
Thanks for checking this out,
