 In order to bring Hábrók back online after an incident we sometimes have to reinstall and reconfigure the login and interactive nodes. Because of this, these nodes will have new server host keys. This means that connecting to Hábrók results in (correct) warnings that these keys no longer match those that had been registered on your system when you connected for the first time.  In order to bring Hábrók back online after an incident we sometimes have to reinstall and reconfigure the login and interactive nodes.
