MyGateway Node Down

Description

4pm, Saturday, Feb 11, 2017 to 4am, Sunday, Feb 12 – Users reported and logs confirm that one of the four MyGateway nodes was not accepting web traffic last Saturday evening.  This would have affected about one quarter of our users and kept them from accessing the site unless they changed their Internet address (moved to another network).  From the logs it looks like the site was compromised in a way that prevented automatic fail-over from taking the bad node offline.  Therefore, users attached to that node continued to be blocked until the node performed a scheduled nightly restart at 4am.  We are investigating how to improve the automated fail-over in the future.
