well the problem with the article is basically that they left out a lot of important detail, like which bare metal servers, how many, where do they host now, did they use cloudfront what about cloudflare did they use an edge cache? what about reducing costs by killing stopping unneeded resources? a lot of their workload looks dynamic. it's also fishy what they wrote here:

> After testing whether Prerender pages could be cached in both S3 and minio, we slowly diverted traffic away from AWS S3 and towards minio.

if they served directly from s3 that would be, stupid?

> In the last four weeks, we moved most of the cache workload from AWS S3 to our own Cassandra cluster.

is also strange. it misses a lot of detail but it does not look like they just migrated away from s3...

(looks like their new hoster is hetzner, from service.prerender.io )
