Summer Works – New Data Centre, Moodle Snapshot and Upgrade.
By Domi C Sinclair, on 3 February 2016
This year UCL Information Services Division (ISD) is closing one of its data centres in London and relocating the technology and services that run from that location to a new state of the art facility in Slough. This is a major undertaking by ISD and nearly all services from finance and HR through to the Digital Education services such as Moodle, Lecturecast and MyPortfolio are impacted.
In order to complete this exercise all Digital Education services will be required to have a limited period of downtime to make the switch from one location to another.
To ensure we minimise the downtime and to avoid two shut-down dates, we intend to combine the migration exercise with our normal yearly upgrade and snapshot process.
As you may be aware from previous years, we normally advertise a period of 5 days of possible outage for our major Moodle upgrade (Friday evening till Wednesday Morning). This year we intend that this period will remain unchanged and that we will complete both the snapshot, upgrade and the data centre migration within the 5 day period. It will be our intention to restore services as early as possible within this 5 day window.
Moodle Snapshot and Upgrade
In response to the survey that went out to all our Moodle course tutors and administrators asking for your least inconvenient downtime window we had 201 respondents, I thank all of your who responded for doing so.
There is never going to be one date that is ideal for all users, however the survey does highlight the dates which would appear to have the least impact for the most number of users. We have also run internal reports within Moodle to identify the period with the least or no current Moodle/Turnitin submissions planned.
The selected date range is from: 6pm Friday 22nd July > 12pm Wednesday 27th July 2016
Please let me make it clear that the period that students will be without ANY access to Moodle will be less than 24 hours (Friday evening > Saturday lunch time). This is the time taken for the team to create the Snapshot which is then made immediately available.
The Snapshot is a complete copy of the live Moodle and provides students with “read only” access to ALL of the material they had prior to the snapshot being taken.
What the Snapshot does not provide is the ability for students to take part in activities, add to or change Moodle for example the following activities cannot be done:-
- Submission of assignments via either Moodle or Turnitin
- Quiz based activity
- Posting new forum topics or replies
Please take account of this when planning Moodle activities during this period.
After the Snapshot is made available there will be a period of time when the current, live version of Moodle is unavailable to allow for the upgrade and migration to take place. During this time, students will be immediately redirected to this version upon entering the normal Moodle URL.
The publicised outage will be until 12pm Wednesday 27th July, as this “at risk period” is required in case any issues arise. The “at risk period” should be treated as if the service were unavailable and no Moodle dependant activities planned for that period.
If the chosen date range affects your course significantly in regard to Moodle usage that cannot be resolved by the use Snapshot e.g. a critical assignment submission or Moodle Exam date that cannot be altered, please contact us at firstname.lastname@example.org and we will work with you to provide the best possible alternative solution for your requirements.
