    UIS have notified us that essential electrical works will be carried out at the West Cambridge Data Centre (WCDC) on 18 September 09:00-17:00. The entire data centre will be switched off all day.

    This will affect many departmental services (several of our servers are hosted in WCDC) as well as other services in the broader University. Many departmental services will be shut down on the evening of 17 September and will remain offline until at least the evening of 18 September.

    We are planning the precise departmental impact and possible mitigations, and will add more information to this page in due course.

    We know however that most departmental-hosted VMs (except GPU VMs) and departmental administrative systems (for example dbwebserver and the underlyng databases) will be shut down for the duration.
