Type of Announcement: Node4 Planned Maintenance

Description:

Service(s) affected: None

Maintenance Window: 6:30am - 7pm Saturday July 12th

Service Outage Expected: No

Length of Service Outage: None

Reason for Maintenance: Node4 will be beginning the installation of new generators this weekend as part of the continuing expansion of DC2. As part of this installation there may be periods where we will be using generator power as work is carried out to integrate these into the mains system. Whenever we will be on generator power, we will still have UPS backup and a full N+N backup generator on standby. Skilled generator engineers will be onsite during the whole process. We do not anticipate any interruption to service as part of these planned works, but we feel it is necessary to inform customers of any change to our normal operating parameters as we continue works on DC2. Work will be carried out between 06:30 and 19:00 on Saturday 12th July
