it's been asked several times in various venues, why didn't the FBI look at the "DNC server", so i went back through the indictment to clarify the question, and took stock of every "computer" or "server" specifically called out. i was surprised that there was no "DCCC server", and that "the russians" (or just the perpetrators) used a US based server in AZ and a "computer" (not a server, curiously worded) in IL.
anyway, for consideration, here's the list:
leased arizona server
10 dccc computers
33 dnc computers
leased illinois computer
DNC exchange server
[unspecified number of] computers of a U.S. vendor (“Vendor 1”)
that's a fair amount of specific compromise, and i wonder if maybe the FBI (even the clean parts, ha) didn't even need the DNC server to verify anything.
if the AZ server was through someone like rackspace or something, and/or regularly backed up - that could be all the evidence they needed.
