Hopefully, they fix it in 4,6. Here's to hoping!
I, too, am in Texas, but haven't experienced a disconnect recently.
However, I have been encountering major lag off and on that has resulted in my character being killed twice at very inconvenient times.
Last night I had some free time to play and was able to be on steady from about 6p central until 10p. Had a lot of lag from about 6:30 to 8, but then it cleaned up nice for the rest of the evening. I figured something to do with upgrades or some such.
