Some popular images seem to load for me, but longer tail stuff doesn't. Maybe they accidentally flushed their edge cache and then their origin couldn't handle the load.
- londons_explore 7y agoCould they be in your own browser's cache? Or maybe in your ISP's cache? Considering the type of content Facebook, WhatsApp, and Instagram host, I'd imagine the cache hit rates to be pretty low for media. They'd be effective for JavaScript/CSS though, which might also be served from the same system
- awirth 7y agoNo, I checked if it was my own cache, and it's all HTTPS so it couldn't have been my ISP's cache either. I compared a few celebrity's instagrams with accounts of friends with many fewer followers. Celeb's images loaded but less and less as you scroll back through time, friends images all 503'd. Still seems to be the case.
- londons_explore 7y agoBy ISP cache, I meant fbcdn running off a dell server in a rack at your ISP...
- awirth 7y agoAh, sure. Down detector's map suggests it's global: https://downdetector.com/status/facebook/map/ https://downdetector.com/status/facebook/map/ Instagram also doesn't seem to be serving hot and cold content from different hostnames/IPs for me, so it couldn't be that either.
