Don't have direct experience with the big winter storm - that was before we moved here - but neighbors tell me power was OK then.
I will say that we get power flashes during pretty much any thunderstorm. It's often enough that I got battery backups for my desktop and routers so I can work without interruption. But mid south is upgrading underground lines throughout the neighborhood right now so hopefully that will improve. I can only think of one extended outage in 2 years, it was about 4 hours long.
We have mid south for internet and it's been very solid. I like that they let you use your own router. I don't have any experience with the other provider, Windstream.
Cell service can be spotty, depending on who you have.
Occasionally Highway 30 gets blocked due to a wreck and you can have trouble getting to/from town. When the Navasota flooded this spring it also blocked 30 but neighbors tell me that's rare - first time in over 10 years.
Water out here is very hard. This house doesn't have a softener but I wish it did.
Where are you building? We're in the older section on Windsor. We have a separate lot here in KO but no plans to build for a few years at least. But we love living out here!
