We are now under large DDoS attack, more than 5Gbit/s. We expect service to return to normal very shortly. Stay tuned.
iOS 11.03 allows you to bypass iCloud completely, but only for devices in Clean mode, with passcode option. This bug happens on iCloud lock activation screen, before you activate your device.
When screen become locked, just turn on it, wait few seconds and press Home -> Wi-Fi, so no need to reboot device again. Not working: Camera, Cookies, Save state on sleep. Working: everything else. Folder sharing with media streaming from PC remains possible, so expect update soon.
Server worked during last half year thanks to exploit that Apple didn't fixed long time. Apple developers just forgot to add letter 'S' to HTTP url that brings as to help page. It allowed to redirect page to iCloud DNS Bypass.
We have started regional DNS servers to speed up iCloud DNS Bypass worldwide. Now we strongly recommend to use one of the new DNS address, that is closer to you. Soon the old servers will be disabled.
