The company that I rent servers from to run my websites (including the SRRP site) has offered me some great deals on new hardware. I still need to do a more thorough cost analysis, but it seems that I'll be able to maintain the same overall performance for about 25% less than what I'm paying now. Or I could pay the same as what I do now and be more future-proof with better performance. Or somewhere in between, I haven't decided yet.
But I have exams for my Master's degree in Information Security coming up in May, and won't have time to get everything set up until afterwards. It should be a smooth transition with minimal downtime -- about a day is the worst-case scenario. This will only affect the SRRP website, not our DOD:S sever.
I'll post an update with a schedule once my exams are finished.
