New 2010 Onoto Fountain Pen
New 2010 Onoto Pens are now available. What better way to mark a significant event than with a magnificent Onoto pen which bears the University of Cambridge shield on the top of the pen cap and, optionally, the shield of your college in full colour, embedded into the end of the barrel. All pens have the words 'University of Cambridge 2010' engraved around a sterling silver band plated in 23ct gold on the cap. Options include gold plated, silver and black acrylic. To order or for more information please see here.Alumni Travel Programme: Fire and Ice
We are delighted to announce our 2011 tour to the Antarctic Peninsula. The towering walls of ice and glistening glaciers of the world's last untouched continent inspire awe, whilst the abundant summer wildlife of whales, penguins, leopard seals and multitudinous birds contrast with the mesmerising yet inhospitable look of the trackless landscape. This trip departs Friday 25 February 2011 for more information see here.

Service Status
This page shows a realtime display of our server infrastructure, green dots indicating an online server whilst a red dot indicates a server that is currently unavailable.
Infrastructure Explained
Our service is configured to utilise multiple redundant servers for critical services. Each box in the diagram is a logical grouping of servers that are able to 'fail over' to each other. As long as one server within a box is available, the service as a whole is available.
Coloured Groupings Explained
To make it easier to visualise our infrastructure, we have colour coded various blocks to highlight their roles in handling your email.In the event the 'AV/GreyListing' servers are busy, email is delivered instead to any of the 'Backup MX' servers who deliver your email onwards as soon as they can.
Nightly backups of email on these arrays are made to 'Mail Backups'.
'Web Service' is responsible for any web based service in particular the website and webmail whilst 'Database Service' stores everything required by various other stages of the service.
'FTP Service' lets you update your website whilst 'Hosting Service' provides website access to your visitors.
Online Times
We also show you how long each server has been online for (where data is available) in minutes, hours or (far more likely!) days. This lets you see if a recent problem you think might have been service related was or not by seeing if a server (or block) came back online around the time of your issue.
Offline Servers
If you do see a red light you can rest assured we will be informed immediately.
Our systems are all fully automated and continually check each other (and from external sources) for availability. The instant a problem is detected that individual server is removed from the cluster and service continues.
Servers will have routine maintenance performed on them from time to time and you will always be warned if any maintenance causes outages (but not if it will not affect overall service functionality).
In addition we sometimes take servers out of the cluster for extended periods of time or new servers that are being prepared for addition to the cluster may appear here before they are actually used. In these cases the server will appear here with a red dot for an extended period of time although there is no need to worry of course as these downtimes are intended.
