User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0 Build ID: 20170323105023 Steps to reproduce: FireFox is the main browser that I use on my Win 7 Ultimate 64-bit PC. Two days ago I tried numerous times to visit the Wahoo Fitness website at www.wahoofitness.com because I wanted to place an order. I've gone to this website without any problems using FireFox in the past. I can still view the website with Internet Explorer 11. In fact, I tested the website with both browsers and FireFox can no longer view it but Internet Explorer can. Actual results: After a delay of several seconds, a "Service Unavailable" message appears. Expected results: The home page of the website should have appeared.
Works for me in Fx52.0.2 x86 on Win10 1703.
Thanks YF(Yang), I tested it again after your comment and it's working again for me, too. That's strange. It wouldn't work for three days and I tried repeatedly each day. It was working fine four days ago (and earlier). Now it's working again. Perhaps the website was updated.
