[openstack-community] [infra] ask.openstack.org offline for upgrade

Marton and I are taking the ask.openstack.org site offline for a couple hours to move it to a new server running a more recent OS, and upgrading the version of Askbot running on it so that support for Google authentication can be restored soon. The server should be offline no more than a couple hours, so expect to find it up and running again by 18:30 UTC. -- Jeremy Stanley
