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: example.com/* => Cache level => Cache everythinghttps://support.cloudflare.com/hc/en-us/articles/200172256-H...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!).If you're fancy you can even programmatically purge the cache when you do CI deploys using the cloudflare API.
