As you will be aware, MOLE continues to suffer performance problems and we are putting together a comprehensive ongoing plan to address this. As part of this process we will be taking MOLE down on several occasions to perform maintenance. The first two periods of downtime are Wednesday 27 and Friday 29 November, this week.
Maintenance will take place 5am-9am this week but it should be considered at risk until midday, and as such no critical activities should be performed during that time. There will be subsequent periods of downtime, which will be communicated nearer the time, but we will try to restrict these to the regular MOLE ‘at-risk’ period of 6-9am on Friday mornings.
The maintenance work will involve moving MOLE onto new hardware with additional capacity. We will also be performing an iterative sequence of software updates and modifications, taking time to monitor the impact of each individual change we make.
We cannot say for sure when MOLE will be returned to reliable full performance service but we will continue to investigate, implement changes and then monitor in a measured, ongoing programme of work until our VLE has been restore to full service.
We are keen to provide regular updates on our progress but do not wish to bombard you with information, so we have have set up an opt-in MOLE-users email list which we will post regular updates about MOLE, including the current work. Subscribe to this list using the link below:
We have also set up a dedicated MOLE maintenance blog which you can revisit at your convenience to be updated on progress:
We apologise for the ongoing poor-performance of MOLE and for the inconvenience caused by the imminent periods of downtime. We are dedicated to resolving this issue and we thank you for your patience.
