On Tuesday 28th October we plan to replace the NX server named bakerloo which hosts nx.inf.ed.ac.uk with a machine named piccadilly. All that will happen is that at about 09:00 on Tuesday we will change the DNS alias to point to the new machine. This change can take some time to propagate so we will […]
Yesterday evening, our SAN storage device satabeast2, suffered 2 disk failures. We can cope with 1 disk failure (RAID5), but following that first disk failure there is a period of time, while the redundancy is restored, that should a second disk fail then data will be lost. This is what happened yesterday. There is a […]
You can now follow us on twitter at @infalerts!

Information Services (IS) also post information about services they […]
The 5th minor update to ScientificLinux 6 (which is based on RHEL6) is now ready for deployment to the Informatics SL6 DICE office and student lab machines. A minor update like this provides us with the opportunity to update important software and fix any bugs which are not security issues (we apply security updates as […]
On Tuesday 26th August we plan to replace the SSH server named hogwood which hosts staff.ssh.inf.ed.ac.uk with a machine named brendel.

Similarily, entitlements can now also be used to limit the visibility of the mailing list archives. Entitlements are attributed to groups of users (or individuals), typically according to their status in […]
We recently added a second NX server, staff.nx.inf.ed.ac.uk. The first NX server, nx.inf.ed.ac.uk, is unchanged. NX is the remote graphical login facility, offering a DICE desktop from a Windows, Mac or Linux machine anywhere on the internet. staff.nx.inf.ed.ac.uk is for staff, research postgraduates and visitors. nx.inf.ed.ac.uk is still accessible to all Informatics users. If you […]
Following the changes noted in my recent article, the Forum network appears to have been stable again. If you’re still experiencing problems, please report them through the support form in the usual way and we’ll look into them. As a separate issue, a number of central University services were affected by a firewall problem on […]
I’m sorry to report that we shall not be upgrading the DICE teaching desktop platform this summer. This means that the DICE teaching platform will be SL6 based for another academic year. We had hoped to upgrade to a free derivative of Redhat Enterprise 7 (RHEL 7) this summer, but unfortunately RHEL 7 has only […]
You may have noticed some periods of instability with our Forum network recently. This has proved hard to diagnose as one of the first things to be hit would be the management interfaces to our network switches, so that obtaining useful data (indeed, any data at all) during an event was problematic. However, we believe […]
