I'm sure it is just as frustrating to the folks trying to fix this. Remember, they have church callings just like you do and have to deal with the same issues you deal with. It has been reported in the forum several times that this isn't a lack of servers or server quality. There are other issues that are not easily or quickly solved.
I'm just a regular member like everyone else and have no special knowledge of what is going on at CHQ with this, but based on what I have read in the forums, thinking CHQ is not aware of the issues and not aware of the frustrations it causes worldwide is incorrect. I think if there was an easy or straightforward fix, it would have been fixed long ago. I don't believe they roll anything out on Sundays - it is just that the load on Sundays aggravates the problems.
