    • Upload speeds Unusable Out of The Blue
      First off I want to say that I have Cox (Las Vegas NV) with their top package that offers 200mb Down and 40mb Up. Everything has worked fine for a long time getting close to those speeds until about 10 days ago where I noticed I could not stream onto twitch anymore at 3000kb upload. I did a ton of troubleshooting on my end everything from reformatting my pc to driver updates to firewall/router/security/cleaning out my PC/OBS stuff... nothing I've done seems to work. The upload speed is so slow now that I cant stream which is a source of income for me and I really need to figure out this issue. Also I just had the ISP come out today and say everything was good (even though the tech didn't know his elbow from his ****hole) Now I log onto OBS or any other streaming service and I within 30 seconds start dropping frames like crazy. My internet speeds are 200mb Down, 20mb+ Upload (which is what I pay for) on speedtest.net but 100mb down/1.1mb Upload on Testmy.net?!?! and now struggle to stream at 3000kbs? I'm at a loss. I REALLY could use some help. Thanks for your time.

    • Automatically choose nearest server for guests
      Look closer at the mobile version.  Scroll down a bit and look in the lower right.  You can see the server's icon.     Mine is showing "Dallas - iPhone Detected"    As for automatically selecting a more appropriate server, TMN does this already too, based on your detected country.  IE is one that's sent to the UK servers.  Here, I'll just share the current country arrays.   $arrayEurope = array("AL","AD","AT","BY","BE","ES","BA","BG","HR","CY","CZ","DK","EE","FO","FI","FR","DE","GI","GR","HU","IS","IE","IT","LV","LI","LT","LU","MK","MT","MD","MC","NL","NO","PL","PT","RO","SM","RS","SK","SI","SE","CH","UA","GB","VA","RS","IM","ME"); $arrayEuropeB = array("DE","DK","NL","CZ","PL","BY","RU","FI","EE","LV","LT","SE","AX","RO","BG","CH"); $arrayAfrica = array("DZ","AO","SH","BJ","BW","BF","BI","CM","CV","CF","TD","KM","CG","DJ","EG","GQ","ER","ET","GA","GM","GH","GN","CI","KE","LS","LR","LY","MG","MW","ML","MR","MU","YT","MA","MZ","NA","NE","NG","ST","SN","SC","SL","SO","ZA","SH","SD","SZ","TZ","TG","TN","UG","CD","ZM","TZ","ZW","SS","CD"); $arrayMiddleEast = array("AF","AM","AZ","BH","GE","IR","IQ","IL","JO","KW","LB","NT","OM","QA","SA","SY","TR","TM","AE","YE","PS"); $arrayAustralia = array("AS","AU","NZ","CK","FJ","PF","GU","KI","MP","MH","FM","UM","NR","NC","NZ","NU","NF","PW","PG","MP","SB","TK","TO","TV","VU","UM","WF","WS","TL"); $arrayAsia = array("BD","BT","BN","KH","CN","CX","IO","HK","IN","ID","KZ","KP","KR","KG","LA","LB","MO","MY","MV","MN","MM","NP","PK","PH","SG","LK","TW","TJ","TH","UZ","VN","RU"); $arrayAsiaB = array("IN","ID","NP","SG","MY","VN","MM"); Defaults associated with those arrays $arrayEurope = uk.testmy.net $arrayEuropeB = de.testmy.net (overrides previous default) $arrayAfrica = uk.testmy.net $arrayMiddleEast = uk.testmy.net $arrayAustralia = au.testmy.net $arrayAsia = cn.testmy.net $arrayAsiaB = sg.testmy.net (overrides previous default) Everywhere else defaults to dallas.testmy.net Note: Dallas, UK and DE being the most popular locations have arrays of servers to meet demand.  We still often call it, "the Dallas server" ... but it's not just one server.   If you see that I've missed any countries please point them out.   You test a lot of different connections, some of them may be detected as "Unknown".  The country identifier is very reliable but there are still instances where it isn't able to be resolved.  In those instance you'll be defaulted to Dallas... unless you're signed in and have already previously chosen another server, in that case the default is overridden to your choice.  As long as you're signed in your server selection will follow you... that's a database driven setting.   For the most part, when you share "testmy.net" with your friends they'll be defaulted to an appropriate server.  If you notice otherwise go to http://testmy.net/database and see what the detected country is.  If it's detected and still defaulting you to Dallas PM me the IP address and I'll be happy to look into it. Thanks for all your support, suggestions and questions.     
    • Hacking the automobile: simple as that
      Jason You car is not a mechanical device. Nope. Your car is “probably the most complex distributed system that you personally own,” Professor Stefan Savage explained earlier this month in a talk at USENIX Enigma 2016 entitled “Modern Automotive Security: History, Disclosure, and Consequences“.   This is why: This are the basic computing features of most any car purchased in the last 5 years. But the computerization of cars began 45-years ago with the advent of the airbag. A typical automobile network is now vastly most complex than what most of us have in our homes.   And there’s a good chance that your “off-the-shelf, unmodified sedan” could be compromised by a third party. “Compromised” as in your brakes could remotely be made useless, as Professor Savage did for this episode of 60 Minutes. The answer to these problems isn’t simply “hire better people and it will all be better,” Savage explained. Cars are vulnerable for a lot of reasons — including the security problems emerging in much of the Internet of Things. Savage calls it “a huge amount of pressure on feature creation.” Often, in the rush to add functionality, security is often not considered or actively ignored.   Additionally, there are underlying issues with code ownership and laws that deny even security researchers access to internal workings of car software. “The thing that parents need to know about smart toys is that they’re new terrain for parents and children, but also manufacturers,” our security advisor Sean Sullivan told Newsweek. And his critique of the connected toys industry is certainly true of the computing revolution that’s been going on inside our cars over the past decade. From OnStar to keyless entry to electric car charging station, two-way digital communication makes vulnerabilities likely if not inevitable.   Car companies seem to have changed their approach and heightened their concern for security after the Jeep hack last summer, which led to the recall of more than a million Chrysler automobiles. But recalls aren’t a very effective way to update cars, given the large percentage of owners who just won’t bring their cars in unless they stop working.   Savage told the story of a vulnerability his team discovered in Generation 8 OnStar units that they decided not to disclose based on the low rediscovery risk. Five years later it came out that GM had updated all of the units even though Generation 8 OnStar “has no ability to do remote updates.” So what happened? “I’m not saying that GM hacked millions of its own cars…” Savage mused. “But something happened.”   Source
    • Automatically choose nearest server for guests
      One small issue that catches me out from time to time is where TestMy chooses Dallas, Texas by default.  This generally is not a problem on a PC as I can clearly see the chosen server at the top right.  However, when testing on my mobile, it doesn't show the current server unless I go into the "Server Selection" page and I remember one day doing tests in one town only to realise it lost my Cookie and ran all the tests with the Dallas server.    When I ask people to run a speed test, the main workaround I use is to ask them to use the URL http://uk.testmy.net/ which forces the use of the UK server.   If it's straight forward enough to work out the country from the user's IP address, one nice feature would be to have TestMy automatically pick the nearest server when the user is not logged in and the cookie has no been set (i.e. first visit to TestMy).   For example, if my cookie expires or I use a PC / browser for which I'm not signed in, it will generally switch back to the Dallas server, even though my nearest server is London, UK.  The following is an example where I opened a private browser window and went to TestMy.net to simulate a first time visitor:  
    • New Survey Suggests U.S. Encryption Ban Would Just Send Market Overseas
      Jenna McLaughlin Feb. 11 2016, 7:00 a.m. If the U.S. government tries to strong-arm American companies into ending the sale of products or applications with unbreakable encryption, the technology won’t disappear, a group of researchers conclude in a new report. It would still be widely available elsewhere. Some U.S. law enforcement officials argue that unbreakable encryption is interfering with legal surveillance of suspected criminals and terrorists. And some members of Congress are pushing for a nationwide requirement that encryption allow for law-enforcement access. But the three researchers — Bruce Schneier, a cryptologist and fellow at the Berkman Center for Internet & Society, Kathleen Seidel, an independent researcher, and Saranya Vijayakumar of Harvard — compiled a list of at least 865 hardware and software encryption products available in 55 different countries. More than 500 of them come from outside of the United States. “The report calls into question the efficacy of any U.S. mandates forcing backdoors for law-enforcement access. Anyone who wants to avoid U.S. surveillance will have 546 competing products to choose from,” Schneier wrote in a press release. “Any U.S.-only restrictions will adversely affect U.S. companies in this worldwide market,” he continued. “Criminals and terrorists will switch to more secure foreign alternatives, and the people who will be most affected are the innocent Internet users who don’t know enough to use non-backdoored alternatives,” he wrote. It’s not entirely clear which overseas encryption products are truly unbreakable, and which have been compromised by government surveillance backdoors. Even so, Schneier and his co-authors insist that “cryptography is very much a worldwide academic discipline” and “there is no reason to believe that foreign-designed or foreign-developed encryption products are any worse (or better) than their U.S. counterparts.” Source
