Is Calgary online yet?


March 29th Cloudflare’s blog mentioned there is now a presence in Calgary but a week later, I’m still not seeing any traffic go there.

From a Shaw cable modem:

[~]curl --head | find "CF-RAY"
CF-RAY: 4078a7e9dcb33b0e-YVR
[~]dig @ id.server CH TXT +short

I tested TELUS DSL (local telco) yesterday and didn’t get to Calgary either, nor does my Rogers mobile phone. I’ve been out a bit over the last week and tried from a few random public hotspots and so far I’ve gotten responses from YVR (Vancouver), SEA (Seattle), YYZ (Edmonton), and once somewhere down in Texas, so depending on the network it seems like I hit anywhere surrounding Calgary, but never Calgary.

Is there any traffic hitting the Calgary site yet? Routing can certainly take a bit of time to settle sometimes, but I’d expect to see some sign within a week on at least one of the major carriers.


Great question… I don’t know the answer, but I’ve asked internally. If you have any traceroutes or other network info which might help us determine which subnets you’re on feel free to add them. :slight_smile:


Sure, can do. Here’s what I can do from where I’m standing right now. I grabbed the IP, traceroute and a dig. I have previously confirmed at these sites that with curl --head that CF-RAY indicates the same city as @’s id.server, but I can cross check locations as I go, if you would like.

Let me know if any alternate information would be useful. I’ll try to avoid repeating providers, but I am testing IPv4 and IPv6 separately as they could be routed differently.


Now on, it says that Calgary (and a bunch of other POPs) are re-routed. Scrolling down says Resolved, so I’m not sure which to believe.


Interesting point. I’ll wait until that clears.

I think it will show green even when POPs are down as long as traffic is routed to a working site. Confirmation from Cloudflare would be appreciated just to know for the future.


Since Calgary reports as being online again (and has for some hours) here’s two more from TELUS.

I retested a couple previous ones just to confirm nothing has changed since I might have initially tested when Calgary was offline. No change.

I checked this twice, the second after disabling cellular just to ensure I was using wifi. Weird. I’ve been randomly checking with curl, but it’s harder to copy/paste from iOS. This is the first time I got different sites from id.server and curl.


Were you able to get any information? I’m still unable to find any network in Calgary that actuall connects to Cloudflare’s fabled Calgary site.


Originally I asked about the PoP itself… no answer. So I filed a ticket with out networking team on the results you found. Will update when we know more.


Did you get any response?

There is one change from my perspective, today:
id.server. 0 CH TXT “yvr01


So it seems like DNS and HTTPS services are now coming from two different locations, neither of them from the new YYC (Calgary) location.


Yeah sorry forgot to update.

Vancouver is the closest place we peer with Shaw, they don’t peer on any exchanges in Calgary.


I could have sworn they did (but of course, things change too).

But not Shaw, TELUS, Rogers (wireless), or any of the other handful of places I’ve tried? It doesn’t seem like Cloudflare YYC has a whole lot of use if none of the consumer/SMB ISPs actually use it.

I did find one network where I hit Cloudflare Calgary (the health network that services hospitals and some other facilities).

Ahh well, nothing you can do on your end. I’ll poke some contacts at Shaw and see if I can find out why Shaw isn’t peering on local exchanges in their headquarter’s city.



Useful link someone passed to me:


Thanks! Okay, that clarifies what I was remembering.

One of YYCIX locations has a full partnership with Shaw, yet they apparently don’t participate in their own facility even though they sell services there.
