More Information
Fri 29 Oct - All systems ran without problems
Thu 28 Oct - All systems ran without problems
Wed 27 Oct - HPC Service Restored & LUVLE Updates
The service is back up and running, however, with one storage blade down the filesystem should be considered at risk of file loss until a replacement
is shipped.
The RAID reconstruction completed overnight with no apparent file system damage, allowing the job scheduler to be restarted this morning.
LUVLE Updates
LUVLE services will be taken down for maintenance today at 14:00 for the purpose of applying a second Hotfix from IBM. We expect this to last up to 60 minutes.
A fourth server has been put into service and the LUVLE Spaces from the following departments have been moved to it: Accounting and Finance, Economics, LEC and Psychology: More Information.
Tue 26 Oct- Engineering network at risk
During the at risk period on Tuesday 26th October work was performed in Engineering building to resolve some outstanding problems with resilience.
There was (between 0700 and 0830) brief periods of network outage whilst diagnostic work was carried out.
WiNet Service Update
10:25am - All Wireless Networks (WiNet) are now running normally. If you experience any problems with wireless connectivity, please contact the ISS Service Desk
Mon 25th Oct - WiNet Intermittent Service
15:45 ISS will reconfigure the wireless networks (WiNet) between 7am and 9am on Tuesday 26/10/2010 to improve the connectivity issues that are currently being experienced. While WiNet is being reconfigure there will be breaks in service.
14:35 The 'lancaster' and 'Eduroam' wireless networks (WiNet) have intermittent connectivity. ISS staff are working to restore normal service.
Fri 22 Oct - LUVLE Stability Update
The work we have been carrying out to improve the stability of LUVLE has been succesful, with the service being available for between 95.7% and 99.8% of the time over the last 3 days. We are continuing to work with IBM to fix the root cause, and are providing more detailed status reports and recommendations through the LUVLE website (follow the 'More Information' link).

Thu 21 Oct - LUVLE Stability Update & Wireless Connectivity
Wireless Network Connectivity Issues
'Lancaster' and 'Eduroam' wireless networks (WiNet) had intermittent connectivity issues across campus from 2pm for about 15 minutes.
LUVLE Stability Update
The fix wehas now been implemented across the LUVLE service and has had a positive effect. We are providing more detailed status reports and recommendations through the LUVLE website (follow the 'More Information' link). More Information
Wed 20 Oct - LUVLE Maintenance & Exchange Email Service Maintenance
LUVLE Maintenance
LUVLE MyModules was unavailable on Wednesday 20th October at 4pm for about 90 minutes. During this time ISS worked with IBM to more fully test the system and identify the source of the stability problems we have been having recently.
To limit the effects on our users, today we will add a new server to further distribute the load.
In addition we are now testing a possible fix on one of the servers and expect the results this afternoon. If positive, it will be put on all servers this afternoon during the scheduled maintenance period. We are providing more detailed status reports and recommendations through the LUVLE website (follow the 'more information' link below).More Information
Exchange Email Service Maintenance
The Exchange email system will be temporarily unavailable between 1pm and 5pm on Wednesday 20th October, for the application of security updates. Individuals should see interruption of service for no more than 30 minutes during this period. More Information
Tue 19 Oct - Pass Rollout
The ISS rollout of the PASS system reached University House, the Reception Building and the Chaplaincy Centre . The Permissive Access Security System (PASS) will ensure that only registered computers can access University computer resources. Additionally, PASS will allow free movement of registered computers from one location to another.More Information
Mon 18 Oct - LUVLE Updates
If you do find your LUVLE space is unresponsive, you should be able to retry successfully only a minute or two later. More details and further updates can be found on the LUVLE updates web page. More Information
Fri 15 Oct - LUVLE Updates
The stability problems we have been experiencing with the system that runs LUVLE continue, though outages should be fewer and shorter now, with the impact minimised as far as currently possible. We will be continually monitoring services over the weekend to ensure continuity, while we and IBM identify the root cause.
If you do find your LUVLE space is unresponsive, you should be able to retry successfully only a minute or two later.
More details and further updates can be found on the LUVLE updates web page. More Information
Thu 14 Oct - LUVLE Update
Over the last few days we have improved the reliability of LUVLE by making some changes to the way the system operates. There have been no outages since 17.35 yesterday (13/10). However, if you experience an instance in which your LUVLE Space is unresponsive, please re-try after 10 minutes.
Other access issues, or any problems with MyPlace, MyPGR, LUMES, Turnitin or the LTG web pages, should continue to be reported to the ISS Service Desk.
More details and further updates can be found on the LUVLE updates web page.
Wed 13 Oct - Ongoing LUVLE Problems
The problems with LUVLE, as detailed below, remain ongoing.
Tue 12 Oct - Ongoing LUVLE Problems & WiNet Maintenance
Maintenance was carried out on the WiNet service. No WiNet access was available whilst work was undertaken.
The problems with LUVLE, as detailed below, remain ongoing.
Mon 11 Oct - LUVLE Problems
Two of the three servers providing LUVLE Spaces are experiencing problems. We are taking three courses of action:
- We are closely monitoring and quickly re-starting servers as needed.
- We are moving LUVLE Spaces to additional servers to share the load.
- We have referred this issue to IBM where it is being addressed as a priority problem.
If you experience an instance in which your LUVLE Space is unresponsive, please re-try in 10-20 minutes. While we are working on this server problem, additional calls or emails to the ISS Service Desk identifying LUVLE Spaces becoming unresponsive especially when you try to load them, will only receive a brief response saying that the problem is being worked on. However, other access issues or any problems with MyPlace, MyPGR, LUMES, Turnitin or the LTG web pages, should be reported to the ISS Service Desk.
Further updates will be made through the Message of the Day (MOTD).
Fri 08 Oct - All systems ran without problems
An issue with Hotmail/Windows Mail being delayed was resolved. Users were made aware that forwarding email to third parties increases the risk of delayed or non-delivered email.
Thu 07 Oct - File Store Maintenance & Mail Delivery Delay
File Store Maintenance
The Central File Stores will be temporarily unavailable between 7pm and 8pm on Thursday 7th October, for important maintenance. This will affect personal and departmental stores (h: and g: drives).
Individuals should see interruption of service for no more than a few minutes during this period.
Mail Delivery Delay
At present the University is generating a lot of mail which is being forwarded to Microsoft Windows Live and Hotmail accounts. Microsoft is limiting the number of messages that ISS can send to them per day and therefore messages may take longer (up to 24 hours) to reach recipients. ISS currently recommends that students should switch off message forwarding in Webmail to ensure University correspondence is received without delay.

Wed 06 Oct - Network Problems in the Management School
A problem with network connections in the Management School has been fixed by removing hardware which shouldn't have been connected to the network. A machine in the management school was handing out IP addresses to other machines on the network . Any machines the rogue server handed out addresses to lost all network access and stopped users from logging in. The rogue machine has been identified and disconnected from the network
