Strange Wireless Hotspot Behaviour
I tried out speedtest.net and pingtest.net using the wireless hotspot to see how it performed under 7.1.0.342. I noticed something strange.
It appears that both sites think I'm located in northern manitoba, on the shore of hudson bay. On one attempt, speedtest ran from a server in yellowknife. After that it ran from a server in saskatoon and pingtest ran from a server in edmonton. In both cases, the servers were determined by ping speed. Anyone have an idea why this is the case? I would have thought that since I'm in metro vancouver, one of the servers here would have been chosen. http://www.speedtest.net/result/1864245466.png http://www.pingtest.net/result/59919352.png |
Re: Strange Wireless Hotspot Behaviour
Yes, it's because of the reverse DNS /IP lookup that the server does. It routes you to the closest server based on IP location, which in this case, it believed to emanate from that location. You're on wireless, so technically, that IP can follow you around anywhere in the country.
Example: my residential DSL is provided to me through a reseller in Ontario, but I'm in Quebec. Their IP address blocks are assigned to their physical address by the provider they buy from, so when I perform the same speedtest as you, it chooses a server in Ontario, some 300 miles away from me. This is all normal behavior. |

This happens all the time on mobile devices. I notice it most often when I post to Facebook whilst tethered because Facebook will think I'm somewhere else in the country entirely.

Re: Strange Wireless Hotspot Behaviour
That's what I initially thought. However, when you run speedtest and pingtest, it says the servers are chosen based on ping speed. It seems strange that irrespective of the ip address, the ping speed would result in a server in yellowknife being the fastest when I am located in on the west coast.

Re: Strange Wireless Hotspot Behaviour
It's about the routing and amount of hops in between...physical distance in a given area means very little when it comes to routing and hops. Each hop in the route can add latency depending on the ISP and equipment.

Re: Strange Wireless Hotspot Behaviour
Exactly, and using reverse DNS will also help them find the best route, but wireless devices use NAT, so the server is picking up the public IP of the router that provided the NAT address to your device, which could be somewhere way different from where you are.

Re: Strange Wireless Hotspot Behaviour
Thanks for the replies. I understand what you mean, but both speedtest and pingtest use ping speed to determine the best server. It's very strange that speedtest picked a server in yellowknife, considering there are so many other servers that are closer to vancouver. It makes me wonder where Bell connects the service to the internet. One would think that they would at least have connections in the major metro areas, but I guess that would be too logical.

Routing and hops!

Re: Strange Wireless Hotspot Behaviour
Generally, the server used will be the closest one (geographically) to your ISP location - from a wired connection. That's the way those sites work. 1st hop would normally be the closest to your network, which would be closest to your ISP. I have seen this forever on wired networks. If I go through say our VPN tunnel, which uses Fibre Noire (Fiber), their NOC will be the 1st hop, since they also happen to host one of the test sites for speedtest.net. If I go through my DSL connection, which is hosted in Ontario, the 1st hope will be right around them, and I'm in Quebec, but my IP block is assigned to the ISP in Toronto. If I go through my cable connection (Montreal based), it will hit a server in Montreal, which is where I'm closest to.
Ping latency is bullshit, since they're generally pinging only one NOC, the one closest to the IP block you fall under. |
Re: Strange Wireless Hotspot Behaviour
I tried another round of speedtest and ping test.
Both sites still think I'm located on the west side of hudson bay. http://www.speedtest.net/result/1872031338.png http://www.pingtest.net/result/60177135.png I ran a tracert to bell.ca. C:\Users\XXXXX>tracert bell.ca Tracing route to bell.ca [198.235.69.32] over a maximum of 30 hops: 1 55 ms 60 ms 49 ms 10.253.82.41 2 46 ms 49 ms 49 ms 172.25.16.90 3 106 ms 59 ms 59 ms 172.25.16.2 4 106 ms 69 ms 69 ms 204.101.4.153 5 1434 ms 664 ms 543 ms dis4-torontodc_Vlan81.net.bell.ca [64.230.206.114] 6 * * * Request timed out. [deleted] 30 * * * Request timed out. Trace complete. C:\Users\XXXXX> I'm very curious where the first four routers are located. |
Re: Strange Wireless Hotspot Behaviour
1st 3 are deep in the US could not get a precise hit but got a physical location, 4th one is in Ottawa. Use this tool to see the location of the servers...
204.101.4.153 IP Address Location, City: Ottawa, Country: Canada | Whois |
