I just went to the Appurify WPT site (appurify.webpagetest.org) and it looks like they no longer have any active devices with which to test.
I know they were bought out by Google but I believe I read that Google was going to still provide a “freemium” service that basically did what Appurify used to do - real device testing from different geo-locations.
I searched around a lot on Google but did not find anything. Does anyone know whether they implemented this? If so, what is it called and can someone provide a URL? Alternatively, is there anyone else doing something similar to what Appurify was doing?
