Forgive me if this should be somewhere else and mods feel free to move it.
Josh asked about Hillary's email server. First of all, I would totally expect the Clintons to have their own email server under their physical control in their own home and administered by a trusted member of staff. This is very common for High Net Worth Individuals as it is the best way to ensure privacy and maintain a record of their business and other dealings.
I know this because I used to own a company that provided IT systems to this group of people. Not weird at all but perfectly sensible and normal, for the 1%.
Each email server has an MX record that is bound to a gateway router. This means that, without too much trouble, a techie could find out what physical building or complex an email server sits in. I've done this many times myself.
There are ways to try to disguise the location of the MX record, but it requires setting up a private WAN (preferably Laser or other hard to hack medium distance wireless method) to another nearby building not traceable to the HNWI. In most cases this is not worth the extra complexity.
