I tried a lot. I spent a good amount of time searching for what the restrictions were in my city. I found news articles describing restrictions, but I wasn't able to locate primary sources or a way to keep updated.

Even with the link you sent me, that site gives no indication that it's a way to get updates on pandemic-related news and restrictions. It seems to just be an emergency subscription. What other messages does it send that aren't described in the FAQs?
