Update on MOLE performance problems, October 2013

As you may be aware, CiCS staff have been working with our suppliers all week to maintain a usable MOLE service whilst investigating the causes of intermittent performance problems.

Following the installation of some patches the MOLE service has become more stable but is still not running at full performance levels. The my MOLE navigation panel is also running at reduce functionality as depicted below:  



Live classroom teaching can now be undertaken with the understanding that some individual sessions may crash or timeout.  However, tests should not be delivered via MOLE.

To continue to provide this level of service we will restart MOLE during its usual Friday morning at risk period to install more patches.  The service will be unavailable 04:00-07:00 and should be considered at risk all Friday.

Updates on our progress is available on our service status page. A history of all updates to date is reproduced below:


Update 4th October 11:00

MOLE has been successfully restarted and remains stable. Live classroom teaching can now be undertaken with the understanding that some individual sessions may crash or timeout. Significant assessments should not be delivered via MOLE. 

Update 3rd October 13:40

Following the installation of patches from our supplier, MOLE is now more stable. Live classroom teaching can now be undertaken with the understanding that some individual sessions may crash or timeout. Significant assessments should not be delivered via MOLE. 

MOLE will be restarted during its usual Friday morning at risk period and will be unavailable 04:00-07:00. It should be considered at risk all Friday.

Update 2nd October 16:10

We're continuing to work on MOLE but its status remains the same: available but at risk and not stable enough for live teaching in a classroom where students are likely to be performing the same actions at the same time.

Update 2nd October 14:00

The MOLE service is still available but at risk and we are continuing to work with our suppliers to fix the bug and restore MOLE to full service.

Update 2nd October 10:42

The MOLE service remains available but at risk. We are continuing to work with our suppliers who have identified a bug and have suggested some promising workarounds which we are implementing. For the time being we still recommend against using MOLE for live teaching in a classroom where students are likely to be performing the same actions at the same time.

Update 1st October 16:05

MOLE is still running and we are continuing to work with our supplier to maintain and improve it. We still advise that MOLE should not be used for live teaching.

Update 1st October 13:30

The MOLE service is still running and we are continuing to work to maintain the service and improve its performance and stability.

However, for the time being we advise that academic colleagues do not use MOLE for live teaching until we can confirm it is working reliably.

Update 1st October 11:15

We are continuing to have problems with MOLE and we are working closely with our supplier to try and resolve this. CiCS staff are working to maintain the service whist investigating the underlying cause.

We appreciate what a disruptive impact this is having and apologise for the difficulty that it is causing. For now we recommend that academic colleagues do not use the service for teaching until we can confirm that it is working reliably.

Original Post 1st October 10:05

The MOLE service is currently running at reduced capacity and should be considered at risk.
