I faced a strange problem today. I have an iPhone 4s with iOS 5.1.1 on AT&T’s 4G network in Boulder, Colorado.

I tried opening this blog of mine on my phone today. I tried multiple times when the bus was moving over many miles and also when I had stopped at a particular location. No show. I asked a friend to open it on his Samsung Galaxy Note (which is also on AT&T’s 4G network) but again, no show.

The blog was constantly giving us a 502 Bad Gateway error, meaning that either AT&T’s or my hosting provider’s servers are configured badly. When I reached my office, I opened the blog on my computer. It worked like a charm. At the same time, it did not load on my phone right there and then.

Upon digging a bit, I found that this is a problem for a lot of people all over the country, specifically on AT&T’s amazing 4G data network. Wonder what else doesn’t work!
