Platte River Networks (PRN) will begin managing the server in early June, with the management of Clinton’s aides Bryan Pagliano and Justin Cooper being phased out as a result. But the Service Level Agreement won’t be signed until July 18, 2013.

The original server is disconnected and shipped from Clinton’s house in Chappaqua, New York, to a data center in New Jersey. (Federal Bureau of Investigation, 9/2/2016) (The Associated Press, 10/7/2015) (McClatchy Newspapers, 10/6/2015)

This takes place three months after the hacker nicknamed Guccifer made public Clinton’s exact email address. However, the process of choosing the company began in January 2013, prior to the Guccifer hack, suggesting the change was at least partially due to Clinton’s time as secretary of state coming to an end in February 2013 instead. (The Washington Post, 9/5/2015)

Platte River will soon relocate Clinton’s server to New Jersey, then replace it with a new server, while keeping the old server running.

May 31, 2013—June 2013: A device is bought to make back-ups of Clinton’s private server, but a Clinton company makes clear it doesn’t want any back-up data stored remotely.

On May 31, 2013, Platte River Networks (PRN) takes over management of Clinton’s private server. On the same day, PRN buys a Datto SIRIS S2000 data storage device, which is made by Datto, Inc. Over the next month, this is attached to Clinton’s server to provide periodic back-up copies of the data on the server. PRN sends a bill for the device to Clinton Executive Service Corp. (CESC), which is a Clinton family company.

CESC employees work with PRN employees on how the Datto device is configured. Datto offers a local back-up and a remote back-up using the Internet “cloud.” CESC asks for a local back-up and specifically requests that no data be stored in the Internet cloud at any time.

However, due to an apparent misunderstanding, back-up copies of the server will be periodically made both locally and in the cloud. This will only be discovered by PRN as a whole in August 2015. (US Congress, 9/12/2016)

However, despite internal PRN emails from August 2015 indicating many PRN employees didn’t know about the Datto cloud back-up until that time, the FBI will later find evidence that an unknown PRN employee deleted data from the cloud back-up in March 2015, meaning that at least one PRN employee had to have known about the cloud back-up by that time.
