How much CDN data do you use?


Well-known member
Currently using KeyCDN for my site's static files (but not images). I am barely using the credits I purchased and now they are set to expire if I don't purchase even more. Guess my question is what files are you sending to your CDN? Are you sending images? (Which I'd imagine will use a lot more CDN data). Or does anyone recommend alternative CDN providers better suited for low use?

I am using keyCDN for everything that is in /data/ I use about 60 credits per month.
I also want to use it for attachments once the conflict between @Xon 's attachment/lazy load addons and @xfrocks bd attachment store is resolved. Or whenever keycdn offers a way to host attachments.

Is everyone just setting their config.php to use /data and /js through their CDNs? Wondering if I am missing some files that could be servered through it.
I used to send all of my images and attachments through a CDN, representing several gig per day in usage, but also ran into a problem with not using enough to cover the minimum annual charge in one year - or have to pay too much in another year to cover overages.

Things got perplexing when I switched to LightSpeed, which would sometimes block my CDN as a potential attacker. There were ways around it, and the service provider did try to make adjustments, but their system couldn't deliver consistently.

Disabling attachments on the CDN did result in slightly longer delivery times for my AU users, but found that most of them were being delivered similar times anyway - because attachments weren't being pulled into the CDN for Australia until needed. The only benefit they realized was on motorcycle pics that were new and being viewed frequently.

When Lightspeed started implementing the newer technologies, and users couldn't tell a difference without the CDN during trial runs, I decided to move my CDN domain to Amazon's Cloudfront CDN service. Configured my XF theme to be the only part of my site using it, meaning that only my site's logo and theme graphics are being served from it. My CSS and JS is currently not on the CDN.

Today, my CDN costs are much lower. I may subscribe to a different CDN and serve all images from it again in the future, but things are working well now.

Hope this helps,
