It shows up if you need a CDN pretty clearly when you monitor uptime from around the world.

The response time for Bitbucket for example is:

100ms from us-east

300ms from us-west

400ms from eu-central

600ms from tokyo

800ms from sydney

(numbers from OnlineOrNot)




Ironic for an Australian co's GitHub alternative to be less responsive than GitHub itself in Australia.


Add to that Github is also in the same region as Bitbucket.


GitHub appears to distribute their traffic between us-east and eu-central:

US East (N. Virginia)

62ms 200 OK

Europe (Frankfurt)

62ms 200 OK

US West (N. California)

175ms 200 OK

Asia Pacific (Sydney)

359ms 200 OK

Asia Pacific (Tokyo)

662ms 200 OK


What happened to Tokyo? :(


Actually I just built a tool to visualise this if you want to check it out:

https://onlineornot.com/do-i-need-a-cdn?url=https://bitbucke...


Do they test full rendering time or only RTT? Also it would be useful to know IP addresses from which test request are being made. Tested a site hosted in Hetzner and got 135ms latency from Frankfurt which is unexpectedly high. Ping RTT from some US east networks to this site is around 120-150ms, how it shows the same latency within DE?


Just RTT - it downloads the whole webpage content (equivalent of running curl <url>)

I run the checks via AWS Lambda for now, might put it somewhere more stable like Hetzner/DigitalOcean for better accuracy.


I'm dense and just saw this. Its awesome fwiw!

If you could do something simple in the style of POSTMAN, but with less options - I'd pay fwiw. Not a lot, but if it existed - I'd want it!

Send a POST request to ${url} with ${headers} and ${body} and tell me how long it took from your servers...that'd be awesome!


That's actually a feature of the underlying platform I work on:

https://onlineornot.com/api-monitoring

If it doesn't quite match what you expect I'd be happy to add additional features!


Nice, thanks for showing it!

I tested on my sass that has a CDN and got scared a little bit, but then did a second call and cache hit everywhere, thank god.
