The connection I'm using now (Compass) peers at AKL-IX but still gets routed offshore to LAX for those IPs that on Spark get routed to HKG, TYO.

Seems this is just the way Cloudflare's routing has been set up, Australian ISPs are also affected

e.g. AARNET https://lg.aarnet.edu.au/cgi-bin/traffic.cgi

I'm not sure what the necessary conditions are so that most if not all Cloudflare traffic gets sent to the closest POP.

Cloudflare also included this for reference which is rather interesting: https://blog.cloudflare.com/bandwidth-costs-around-the-world/

Kraven:
Thought I'd try a few websites that use Cloudflare to see where they are being served from on BigPipe (Spark):

geekzone.co.nz: HKG
bunnings.co.nz: SYD
mitre10.co.nz: SYD
ascent.co.nz: HKG
thewarehouse.co.nz: NRT (Japan)
hauraki.co.nz: NRT

Tip: you can go to /cdn-cgi/trace on any website using the Cloudflare CDN to find out what location you're being served from. eg. www.geekzone.co.nz/cdn-cgi/trace

This what I get on Slingshot

geekzone.co.nz: AKL
bunnings.co.nz: AKL
mitre10.co.nz: AKL
ascent.co.nz: AKL
thewarehouse.co.nz: NRT
hauraki.co.nz: AKL

NRT? gosh... guess there is more to do still @sounddude ;)

on a more serious note, thewarehouse seems to be hosted by Instart Logic not cloudflare.

Japan is pretty much local for us with our new cable system from Perth to Singapore :-)

The colo is the origin server. Cloudflare does not host anything (except workers}.

Unfortunately BGP doesn't take into considering things like latency and congestion. Its all down to AS Path length (how many networks is has to route through).

So yea, even though there might be a truly better route, it could still go another way.

Internets must be pretty good in the Middle East... wonder how much of Cloudflare is blocked there lol

Network for learning doesn't appear to be using APE anymore, despite N4L's PeeringDB page shows APE as a peering exchange and NZIX's APE peers list shows N4L as a peer.

Perhaps depeering was part of the managed network upgrade?

Whilst this topic has been on-going for a while, I just did some tests using some different networks. Which Cloudflare Datacenter they connect to when trying to get to Geekzone.

ISP / Network
Cloudflare Colo
Country

AS9245 COMPASS NZ
SYD
Australia

AS4771 Spark New Zealand Trading Ltd.
NRT
Japan

AS9876 NOW New Zealand Ltd.
AKL
New Zealand

AS9500 Vodafone NZ Ltd.
LAX
USA

AS134378 Alchemy Networks Limited
AKL
New Zealand

AS56030 Voyager Internet Ltd.
AKL
New Zealand

AS131296 REXNETWORKS LIMITED
AKL
New Zealand

AS133579 MYREPUBLIC LIMITED
AKL
New Zealand

Using Powershell you can test this for yourself:

# Gets the ISP/Network
Invoke-RestMethod http://ipinfo.io/json | Select -exp org

# Gets the Cloudflare Colo Location you are connecting through
(Invoke-WebRequest 'https://www.geekzone.co.nz/cdn-cgi/trace' -UseBasicParsing | Select-Object -Expand Content) -split '\r?\n' | Select-String -Pattern 'colo=(.*)' | % {"$($_.matches.groups[1])"}

Clearly it seems some of the big players are still not Peering with Cloudflare after so many years, which is a bit sad to see.

I actually thought Vodafone peered with Cloudflare.
