Sean Posted June 2, 2017 CID Share Posted June 2, 2017 Lately when I have been trying any multi-threaded test, it has been quite erratic. It generally jumps straight to 25-50% the instant I start the test and it quite often gets stuck around the 80-90% mark. This is based on picking the UK option and testing on various devices (phone, laptop, desktop, etc.) and connections (home, work, LTE, etc.). As the test in progress screen shows the list of hosts it tests with, I took a screenshot of it and pinged all the hosts it showed. The culprit appears to be the UK2 tests: The hosts starting with 'uk.', i.e. uk.testmy.net, uk.testmercury.net, uk.tracemy.net, uk.testmymobile.net and uk.tmnstatic.com all pinged with an average of 23ms, so these seem to be fine. The uk2.testmy.net and uk2.testmercury.net both pinged with an average of 141ms, so these seem to be pointing to US or other long distance hosts. The uk2.testmymobile.net, uk2.tmnstatic.com and uk2.testmy.net hosts all fail to resolve the host name. This probably explains why the test skips the first 25-50% as the script probably detects the failed host lookups as these pieces completing their download. The uk2.tracemy.net timed out, even when I tried this in my web browser. This probably explains why it gets stuck around the 80-90% mark. Update: An example from Fiddler showing the host issues while a multi-threaded test takes place: Link to comment Share on other sites More sharing options...
Sean Posted July 9, 2017 Author CID Share Posted July 9, 2017 I just want to check if anyone had a chance to look at this issue over the past month. From a quick check, the UK server with the multithread test is still picking unresolvable hosts in each test: The Frankfurt (Germany) one seems to be fine, i.e. not one 502 error after running multiple tests: CA3LE 1 Link to comment Share on other sites More sharing options...
CA3LE Posted July 9, 2017 CID Share Posted July 9, 2017 Thank you Sean! This has been corrected and it now checks the availability of the server as it should. Was only affecting the UK selection when you specifically targeted UK by itself. Great catch! Link to comment Share on other sites More sharing options...
Sean Posted July 9, 2017 Author CID Share Posted July 9, 2017 No problem - Multithreaded test with UK server now working fine here... This now brings up the expected ~3.9Mbps for my DSL connection. CA3LE 1 Link to comment Share on other sites More sharing options...
