In answer to a ticket entitled "Not getting an IPv6 prefix today",
here is what the help desk told me:
> Currently XXX have IPv6 services turned off due to some ongoing investigations
> with this service.
I use them too and have been through a similar experience with the help desk. Their answer on Dec 5th was: "At
the moment our network engineers are still investigating this issue and
we will not be updating the network status page until we know more
about the problem."
I responded that "that custom and usage suggest that issues regarding the network would usually be advised to users as they occur rather than once they are resolved".
