CSPAN not being televised for a week now.

For about a week now CSPAN is not being televised here in Oakland, CA. Usually it's on Channel 23. The channel line-up still shows Channel 23 for CSPAN. But when I go to Channel 23, it is televising the QVC shopping channel. I have looked all around on different channels for CSPAN, but I cannot find a channel that is televising it. CSPAN 2 is still being broadcast as advertised on Channel 109 and CSPAN 3 is being shown on CSPAN 3. Can someone please fix it?

And when will we get a high-definition version of CSPAN on TV?
