OUTAGE: five bridges across Mississippi destroyed

[Sean Donelan]

Now that I have your attention.

My intent with the DLR discussion was to find out how we can estimate,
predict, simulate how robust the Internet really is; not debate vendor
certifications.

Several telephone companies, working together, simulated what would
happen to the public telephone network if five bridges across the
Mississippi river carrying fiber optic lines were destroyed.  The
result was the public telephone network was unaffected, according
to the participating telephone companies.  I believe this was
considered the worst scenario at the time.

Has anyone, or any group of ISPs done a similar analysis for data
and Internet traffic?
