S3 was down
Quick tip for those using static (jekyll, hugo...) sites on s3: If you have cloudflare in front of it, you can turn on aggressive html caching by creating a page rule: <i></i>example.com/* => Cache level => Cache everything<p><a href="https://support.cloudflare.com/hc/en-us/articles/200172256-How-do-I-cache-static-HTML-" rel="nofollow">https://support.cloudflare.com/hc/en-us/articles/200172256-H...</a><p>This downtime made me realize we weren't caching any html on cloudflare. I just turned it on and all our static sites are doing fine now (and our bills are smaller!).<p>If you're fancy you can even programmatically purge the cache when you do CI deploys using the cloudflare API.
