Did Comcast Houston Get Slower?

Last year we were getting 28mbps Using Comcast internet, with an upload of 2.5 mbps. Some crummy local AT&T sub-contractor TM Construction or something like that, cut our live and refused to care. So I patched the line with a splice. I think it was a holiday 3 day weekend. SO I had to do it myself. We still got 28 mbps down and 2.5 up. Our internet was fine. A couple months later, TM construction came back out and wouldn’t you know it, they cut our line again. So this time we had Comcast come back out and replace the whole line with this heavy duty orange cable. Our internet was peaking at 30mbps. We held out for a few months.
But here recently our internet speeds have drop tragically. We are now getting 3 mbps down and oddly enough our upload speeds increased to 3.5 mbps down.
I was told a couple months ago that the speeds are supposed to increase to 50mbps near Humble area.
I can only assume that right now they are upgrading the cables or whatever and right now there is a crummier connection.
How is your internet speeds in the Spring and Humble areas? What is your bandwidth in this area?
