Such a page has both dynamic and static information in it. If you don't have Internet access, that static info can still be helpful. A QR code can hold 2.9 MB of data. I'm imagining a QR code that contains the static information, and a small script that checks for connection and then redirects to the full page that also has the dynamic info. A QR code on an eink screen that gets remotely updated over LoRA could even include the dynamic info.

#42Seeing how it hasn't survived the HN hug of death... Not sure how you've built it but consider putting it behind a CDN or something and caching the responses, esp since you're trying to pull live data

#43I appreciate the idea, but as others have mentioned it seems like for something like this to be useful it really needs to be well thought out and tolerant to extreme spikes in traffic.
I might be wrong here but it looked like the responses from the server are chunked, which I _think_ precludes the use of a highly optimized cache response e.g. from a CDN. Assuming that's true (very open to correction of course!) I wonder why this would be.

#44The font size is too small for emergencies on mobile devices. You need to consider that users might be in a panic, may not have both hands free to zoom in, and their vision could be impaired by smoke or other factors.
Thank you. This has been patched.

#45Others have mentioned this but looks like fires from close to ~20 years ago are still showing up as "active emergencies"[0]. Shows the Nash Ranch fire as an active emergency but it was declared in 2008. [0]: https://safe-now.live/c/us/co/colorado-springs/
Thank you. This is fixed.

#46I'm seeing fires from 1999. https://safe-now.live/c/us/al/
Thank you. This has been patched.

#47I would suggest increasing font-size, looks too small
This has been patched. Thank you.

#48I think people would be more interested in the heavy emergencies, not just the ultra light ones
You are correct. This has been patched.

#49It appears the site couldn't handle HN traffic or maybe the site owner took it down. Regardless, a project like this needs a lot of thought put into it to be something that people can rely on during times of crisis. If it can't handle a surge in traffic from HN, it won't be able to handle a surge during natural disasters.
Works for me 10 minutes after your post. I'm happy to be part of the unintended load test.

#50It must be able to cache it's all content in browser. I guess to do it it properly you need to make it PWA.
Idea is to keep it light and accessible. PWA would be data heavy. The use case is in the article linked in the post description.
