These days we expect the internet to be with us wherever we go. We catch up on emails on the bus, video chat with the fam on business trips, and check out cafes from our phones while on vacation. But there are still a few places on Earth we think of as flat-out inaccessible—as too remote even to connect to the world wide web.

You might be surprised, then, to know how far-flung the Speedtest results we see truly are. From the isolated to the uninhabited, we’re curious about what the internet looks like in unusual places. In honor of the summer travel season, we are sharing data on some of the most interesting and far-out tests we’ve ever seen with #FarFlungInternet. And we’re starting with Mt. Everest.

What’s the internet like at Mt. Everest?

Mountaineers train (and save) for years to finally summit this epic peak. But they don’t leave the internet behind until they’ve departed base camp. Somewhere between excited emails and social posts, some of these climbers are taking a Speedtest. Here’s what the internet looks like at 18,000 ft. in the Himalayas.

Everest Link bills itself as “Extreme Internet” and we’d have to say they’re right. With more than 200 Wi-Fi hotspots located in more than 40 villages in Nepal, they not only have the highest network in the world, they probably have one of the most difficult working zones as well—including below freezing temperatures and low oxygen levels. And because their access points are so remote, they rely on solar power, the only electricity source available. Everest Link CEO Tsering G. Sherpa describes the setup at the Everest South Base Camp by saying, “at 5,320 meters altitude we have a solar powered cnPilot E500 outdoor Wi-Fi hotspot” using a TP 650 wireless backhaul from Cambium Networks.

Everest Link is the only ISP we saw data from at Everest’s South Base Camp and the speeds were much better than we expected. We don’t know if the camp got more crowded on those later dates or if something else happened, but there is internet on Everest. Even if the ping’s a little slow.

Our analysis spanning June 2016-June 2017 turned up only those five tests in April 2017, likely because that’s the peak of climbing season for Everest. We also checked for Speedtest results from the North Base Camp in Tibet, but found none. That doesn’t mean there’s no Wi-Fi up there, but it does mean we can’t verify the speed of anything offered.

Not only are we excited to see parts of the world we may never get to visit, but we also really want to understand what the internet is like outside our daily lives. So, be sure to share your findings with us so we can share them with the world.

In our coverage of the fastest airports on each continent we left one out — Antarctica. Because, as much as we’d love to, we do not have a ton of data from Antarctica to tell you which airfield has the fastest Wi-Fi. But being off the beaten path is kind of the point of visiting Antarctica, isn’t it?

We’re actually delighted to be able to share any data from Antarctica with you at all. Normally we’d sift through data and aggregate it before it’s analyzed to make sure you’re getting a really reliable look at average speeds. Given that there’s nothing average about Antarctica, though, we’re sharing raw Speedtest data from July 2017 for tests taken on mobile Wi-Fi and cellular networks.

Mobile Wi-Fi

During that time we saw three tests over Wi-Fi at field stations (that also have air strips):

These research stations are spread far and wide with one each on the Antarctic Peninsula, East Ongul Island, and King George Island.

Based on those tests, we’d say that there definitely is internet available on Antarctica, but in most cases the speeds are glacially slow. Which is what we’d expect from a continent served entirely by satellites. According to an AMA with a Utilities Mechanic at McMurdo Station, “The internet is fast enough to browse reddit, but they restrict the bandwidth to social media websites and youtube, because EVERYONE is trying to use these all the time and the science teams have higher priority access. Online gaming would only be possible in the really early hours of the morning, and even then the ping would be incredibly high.” His Speedtest result from January 2016 showed a download speed of 1.79 Mbps and an upload of 0.82 Mbps with a ping of 1969 ms.

Cellular tests

We also saw one test over cellular networks in July that occurred near Terleckijtoppen Peak and somewhat close to Tor Field Station. This was by far the fastest test result we saw in all of Antarctica during the time period we studied:

There is 4G on Antarctica. Argentina’s Movistar launched a 4G network at Marambio Base in January. We haven’t seen any tests over it yet, but we’d like to. If you’re living, working or traveling in a remote location on the planet (or off!) please take a Speedtest and share your results with us using the hashtag “#FarFlungSpeeds”.
