Unable to reach Cloudflare's local PoP in Yekaterinburg, Russia (SVX)
I am in Yekaterinburg, Russia (SVX), and as https://speed.cloudflare.com/locations says, Cloudflare has a location here. However, I can't access it and traffic is routed to Moscow, Russia (DME). Also tried three other hosting providers and two home ISPs, same problem.
Then everything worked from the wifi connection of the Ural Federal University (in Yekaterinburg), only 1ms latency. And this is the only ISP that routes to the local PoP in Yekaterinburg.
Is the location in Yekaterinburg private or something like that?

What website are you trying? Would try https://cloudflare.com/cdn-cgi/trace
here's what the map at speed.cloudflare.com shows :gif_spinthink:
Some PoPs only have capacity/bandwidth for Enterprise sites
sounds like more of a routing thing then
The closest PoP doesn't mean the fastest. Your internet provider may be backhauling all connections to Moscow, thus making SVX way higher latency
how would this make SVX higher latency if it isn't reachable for me?
There are some locations which only have capacity for higher plans, and then there's just generic routing stuff. Your ISP has the final control at the end of the day. Perhaps there's an internet exchange your ISP isn't on, or direct peering just your library's ISP has, etc
because if your ISP backhauls everything to Moscow, going to SVX would go SVX -> Moscow -> SVX
instead of just connecting to the local moscow one
Routing and capacity just isn't as simple as the geographic closest. As long as you get decent latency I wouldn't worry about it/not much you can do
I doubt it does, that would be a very strange routing that I've never encountered with the providers I've used
the thing I don't understand is why pinging something like
1.1.1.1 (also tested with some IP from Spectrum) from the university network routes to the local PoP and no other ISP in the city doessounds like everything from the university goes to the local pop, no?
traceroute and see what it goes over. Might be an IX or something
then traceroute normal connection and see how it's routed
A bit off topic but are there more details about how pops are distributed by plans? Im trying to figure out if there would for example be any difference between Free/Pro plans, or if the additional pops are mostly unlocked by Enterprise plans
https://blog.cloudflare.com/meet-traffic-manager
Traffic Manager then identifies how much traffic in each plan we need to move, and moves either a proportion of the plan, or all of the plan through Plurimog/Duomog, until we've moved enough traffic. We move Free customers first, and if there are no more Free customers in a data center, we'll move Pro, and then Business customers if needed.

Some are just straight up Enterprise/Argo though, probably based off bandwidth price/limited capacity or something else
I have this as well if it helps: https://debug.chaika.me/?findColo=true, although not very scientific
Awesome, thanks for the fast & informative reply!
I didn't really clarify the traffic manager part, so if it helps to clarify, the ones Traffic Manager is responsible for are PoPs which are free/lower plan routable but simply out of capacity. Some are like that, and some are just locked behind plans. There's also ISP Routing which is a whole other ballgame.
For more anecdotal data, I know there's been issues with DTAG In Germany Routing free plan to EWR/US East Coast, and I know that mutiple people have reported Pro routing goes to local German/European PoPs
In places where bandwidth is expensive like APAC is where I would expect to see more of those Enterprise-only DCs. Perhaps because there is just such limited capacity Traffic Manager just never has a chance to allow lower tiers on, or perhaps just because of how expensive it is
Was a fascinating read, thanks again!
Curious how this all translates to real life and if there are actually noticeable day-to-day differences between for example identical sites receiving identical traffic depending on their plan. I guess I'll find out soon enough as we are getting closer to having to switch plans up anyway!
