Change to Planned RDF Downtime for UPS Battery Replacement

The RDF has built-in UPS systems (uninterruptible power supply) to help prevent data loss and corruption in case of a power outage. The batteries in these UPS systems are now approaching the end of their life and have to be replaced. The replacement work needs to be carried out with the RDF offline to reduce any risk of data loss during the process and is required to be completed before the actual battery end of life date.

We had planned to replace the RDF UPS batteries in the week of 5 March. However due to the severe weather the external contractors due to carry out the replacement work have had to postpone their visit to us. We have rebooked the work for the week starting 19 March 2018.

This means that this week, starting 5 March, the /eprsc, /nerc and /general file systems, RDF, DAC, DTNs, GridPP and access to JASMIN will now be available for use. The week of 19 March the /eprsc, /nerc and /general file systems, RDF, DAC, DTNs, GridPP and access to JASMIN will all be unavailable. We hope that the work can be completed in less than 5 days and will let you know if the RDF is returned to service early.

We will update our status page ( ) and remind you of the work planned for the week of 19 March nearer the time. We apologise for the inconvenience caused and please contact the ARCHER Helpdesk if you have any questions or concerns.
