i remember places like Chicago Board of Trade also being affected
wasn't it construction or some other event that resulted in a break
in subsurface dam/barrier that was designed to keep the lake out?
note that even if the computer rooms aren't there ... lots of the
related utilities, power backup, etc ... frequently are.
this is akin to the multitude of backhole vulnerabilities; prossibly
one of the most famous was the isolating the new england internet
several years ago. supposedly the original infrastructure had
carefully laid out diverse routing for nine different circuits running
over nine different physical trunks. over the years, while nobody was
paying attention, all the circuits were eventually consolidated into
one physical trunk ... which one day was attacked by a backhoe and
taken out.

Under most of the Loop area, and west and north of it, there's an old
system of "Delivery Tunnels", dating
back to the early 1900's and used mostly for delivery of coal and
merchandise and the removal of ashes. A
contractor was driving "piles", essentially telephone poles, into the
river bed to improve protection for a bridge
when he drove a pile into the tunnel that crossed under the river at
that point. When IT exploded in downtown
Chicago, the tunnels were pressed into use as cable races between
buildings and the doors from basements
into the tunnels couldn't be closed. At the time of the flood, I worked
in the Chicago Board of Trade (CBOT)
building and my company, Board of Trade Clearing Corp., declared
disaster and moved our operations to
our DR provider's site in Northbrook, where we stayed for two weeks. The
CBOT building had 46 feet of
water in basements and sub-basements.
The tunnels now have concrete bulkheads installed on both sides of the
river.
