The IUCr listservers are now up and running again. Please see the message from the SysAdmin below.

Several posts that were held over have already been re-posted, so if you do not receive any messages with [SA_Scat] at the start of the subject line in the next few hours **and would have expected to**, it is likely you will need to re-subscribe to the list.

I can confirm that **all** IUCr lists were affected.

Dear List Members

Server hardware problems following recent scheduled maintenance have necessitated reversion to an earlier copy of the membership list for sa_scat and other IUCr-hosted mailing lists.

If you thought you had previously unsubscribed from the sa_scat list, or this message has gone to an earlier email address for you, please accept my apologies and unsubscribe (again), by visiting


or by sending a message to sa_scat-request at iucr.org<mailto:sa_scat-request at iucr.org> with the word "Unsubscribe" in the Subject: line.

If you know of any colleague who is a subscriber to the list but who does not receive messages, please advise him or her to resubscribe using the same web page:


Some of the local archived messages at mailman.iucr.org may also have been lost in the system reversion. However, a complete archive is available on the main IUCr web site at


I apologise again for any inconvenience caused.

Subject: [Neutron] Problems with IUCR mailing lists

There will be several subscribers to this mailing list who were also subscribed to mailing lists belonging to the IUCr such as 'sa_scat' (for small-angle scattering).

Between Jan 28 and Feb 2, routine maintenance to electrical infrastructure at the IUCr HQ resulted in the failure of a number of servers.

Recovery is proving to be much more complicated than anticipated and, unfortunately, confidence is not high that the list archives and subscriber lists can be completely rebuilt.

The consequences of this are:

-          It is unclear which lists are affected; though sa_scat is for certain

-          No posts will have gone out on affected lists (the last post sent out on sa_scat was 09:44 on Jan 28) but any posts sent to these lists in the meantime **should** have bounced back to the author

-          A resolution may still be some weeks in the offing

-          It is likely that many list subscribers will need to re-subscribe once the system is up and running again

I am in contact with the IUCr IT Team and will post further updates as and when information is available.

In the meantime please circulate this information to your colleagues and other relevant forums.
