Are there known signal issues in Austin?

Thanks, once I posted my message, I reached out to support using the chat tool on the web site.  I was told there was an upgrade process under way and that, indeed, other customers were affected.  I also just got back from running errands and while I was out, I stopped into a T-Mobile store.  They confirmed that there have been cell tower issues since last week's power outages and that while there have been improvements in some areas, there are still areas with weak signal issues in Austin. They were completely unaware of any upgrades in progress.  Though they said it's completely possible that there are also upgrades under way.  As far as they were concerned, most issues stem from lingering problems since the power outages.

I find it pretty disappointing that T-Mobile provides no information about known issues with weak signal on their web site.  Sigh.
