LSR's ISP was in the process of cleaning up their IP space, and requested we update our IP address to a new area. We happily obliged, and went through the processes required. There was very little down time identified and the process went generally smoothly.
While tackling this process, our technical admin team took the opportunity to put additional measures in place to enhance security and spam prevention - We added DKIM and DNSSEC services (and fixed a few bugs while at it). This should help with ensuring email from LSR gets to where they need to be.
