I like this! I noticed that the weather for some Bay Area counties seem to be getting zeroed out for temperature.

(both say: Weather Now 32°F / 0°C - Sunny )

What would be a good book to have in the house that could help me in as many emergencies as possible, but still be portable enough to actually bring when fleeing the house or something?

Alternatively, what would be a good bigger book for the same goal and/or be more about long term survival in case of being trapped in the house long?

The UK emergency phone number is 999, not 112. Ugh. Don't make a website like this without verifying the information is correct please!

112 and 911 (US) work on almost every mobile phone anywhere in the world. It's part of the GSM/UMTS standard. 999 is supported with either no SIM card or a UK SIM card. See §7.1 here: https://www.ietf.org/lib/dt/documents/LIAISON/file562.pdf

They also don't require a phone to be activated in most countries. I believe there are some exceptions in EU countries, but in the US it just needs to have a working antenna and be in range of a tower.

Seeing 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

It was never down - it was being patched and redeployed based on feedback here. Webapp is light enough to handle 10000 concurrent hits.

I can't tell much about your infrastructure, but memcached would probably increase that by several orders of magnitude. The NGINX module is pretty simple: https://nginx.org/en/docs/http/ngx_http_memcached_module.htm...

Cloudflare with Cache-Control headers is even simpler if you're okay with adding Cloudflare as a dependency.

From an ASN lookup, it appears you're hosting on Oracle Cloud, so Cloudflare would also give you free data egress: https://blogs.oracle.com/cloud-infrastructure/why-cdn-client...

Their Always-On feature would also help if Oracle has an outage.

I like the general idea, very lightweight and more likely to remain accessible when an emergency is overloading the mobile networks.

I've been working on a similar idea for travelers, https://travelsafetydata.com/ It's pulling the travel advisories from US/CA/UK/IE/AU/NZ and aggregating the results/information to help you understand the risks of different countries. It also pulls from other sources for basic country info/risks (eg. women, lgbtq). Yours is way lighter weight and focused, very cool!

Lol what the heck? Both UK and France are getting yellow flags because of terrorism. Seems absurd to me but perhaps it's good to get multiple viewpoints.

What is absurd about that?
