I keep getting a "502 Bad Gateway" error on my ipad

I'm getting the same thing. All day. Has anyone called yet, or have they posted a known issue yet?

Same thing here...rebooted, hard rebooted, cleared cache and browser history, nothing...

I'm on an iPhone 4, I have all the latest software updates.

Finally got it to work by clearing the cache, history, and then doing a hard reboot.

Just a hard reboot alone wouldn't do the trick.
Seems to work now.

Same here. Only a problem on both of our iPads, not on our iPhones. I am able to retrieve and send email, but no Internet access via Safari or on alternative browsers.

Working fine now...didn't do anything on my end to fix it. Must have been an Apple server issue or more likely AT&T.

Y'all probably needed to add a VPN to unlock the internet security for the devices
