Cloudflare being unable to handle 100MB of traffic over 5 minutes sounds like itsfoss failed to set something up properly. The link preview is a fraction of the total page that would have to be loaded for each individual user no matter where they came from.

ActivityPub itself could more intelligently cache or display the content but something doesn’t add up if Cloudflare can’t handle that kind of traffic let alone Hacker News traffic.

They've set their headers to prevent caching by cloudflare. max-age=0

The images arn't the problem, it's their dynamicly generated page, even if the content is pretty static.

I believe cloudflare is just letting their requests go through and their webserver can't handle it?

What's the point of using Cloudflare without caching?

Cloudflare has some other features like a Web Application Firewall (WAF) and bot protection/filtering (which seems like it would solve their problems too?)

From the article:

> Presently, we use Cloudflare as our CDN or WAF, as it is a widely adopted solution.

To me, it sounds like the author isn't really familiar with the difference between a CDN and WAF is; or familiar with Cloudflare beyond it being a popular thing they should probably have for that matter.

vbezhenar: They've misconfigured something and the page itself is marked max-age=0 which disables cloudflare caching. I'm also betting nginx isn't caching either.
