I think you're leaving out a very viable possibility in your summary...
What if BoA took a proactive approach and shut down their SQL environment
(even though none of us known conclusively if they're a SQL or Oracle shop)
to verify that it was in fact clean and not compromised. When you're
talking about access to billions of dollars, it's not worth taking a chance.
They might have actually followed proper security protocol and verified
their systems were clean before re-activating them.
Just a thought.

Let me summarize, then ask a question:
a) BoA uses the public internet for ATM transactions. The public internet
was so dead, that every one of thier ATM machines was dead for many hours,
even many hours longer than the public internet was dead.
b) BoA uses it's own network for it's on ATM transactions. Somewhere on
the a public to private connection, a firewall wasn't doing it's job, or
there wasn't a firewall. Things were broken for a while, until they were
able to fix all thier SQL servers.
I guess my point is, if it were a), not every ATM would be dead all the
time, and things would have been fixed in only a little while. Not many
internet 'backbones' (at least ones BoA would have used for this
application) were down as long as BoA's ATM's were.
On the other hand, I think it's more likely that BoA had unprotected SQL
servers, and they got it. It took a long while for BoA IT people to make
it out of bed saturday morning to fix the problem.
I still clearly say that I don't know what happened, and I did make
assumptions (as I said in the original mail) -- but I'd still place my
money on b).
