I can scale up our worker count as needed, but we keep it at a minimum since our Azure bills are already insane. Fun tidbit, there's a little counter on the bottom right which tracks live app circuits on the site, we were cracking thousands yesterday, normally it's ~5-10 at most. Did NOT anticipate having this kind of attention from a comment, and we were out climbing in Boulder Canyon when the bulk of the traffic hit the site.
Why don't you host it yourself if the kids is so small on a normal day?
