[arch-mirrors] If your are syncing of UK2, switch to LeaseWeb

[Jakob Wadsager]

Hello,

Our uk2 mirror has had some problems recently, and unfortunately they
haven't been resolved yet[1]. Therefore we recommend that all tier 2
mirrors that sync off the uk2 mirror switch to our LeaseWeb mirror.
Feel free to switch back to UK2, when the problems are resolved.

[1]I've been told they're working on it though.

Best regards,
Jakob
