These guys charge $550 for a measly terabyte of bandwidth?

If you get a dedi on a 10Gb/s guaranteed port and it works out to more than $3 / TB, you're probably getting scammed. How does "serverless" justify 150x that? Are people hosting some silly projects really dense enough to fall for that kind of pricing?

Just get a $10 VPS somewhere or throw stuff on GH pages. Your video game wiki/technical documentation/blog will be fine on there and - with some competent setup - still be ready for 10k concurrent users you'll never have.
