Thanks for the update — was wondering what had happened ;-)

Thank you for posting this so quickly, Michał, and for dealing with it promptly at odd hours.

This week, IE has been hanging a lot when I try to access custom domains. It times out at

I regularly need to clear my cache in order to get back in. For me, it's an annoyance. For many of our users, it's a roadblock.

Any recent changes that would cause this?

Thanks for the explanation anyway. This morning we got a few alerts from our monitoring service, and we were wondering what happened. It's nice to have such a transparent service provider. :-)

I discovered the reason why I did not get notifications about server problems. I rely on notifications sent by email to a special email account that instantly pushes every new email to my iPhone. But the phone for some reason could not log-in into the cellular network and was working only with my WiFi.

Now the thing I learned: Push notifications do not work with WiFi only when the phone is in "sleep" mode, because WiFi connection is closed to save battery. Without 3G/Edge connection, the phone does not have an open internet connection and cannot receive messages. When I touched the phone to check the time, I instantly got about 50 emails.

To prevent this, the simplest solution is to go back to SMS notifications as the second delivery channel.
