[Kelvin-users] [Parsons-users] Cluster Downtimes August 2017

[Sean McGrath]

Dear all,

Again, apologies if you receive this mail multiple times.

The power outage that was due to happen today has been postponed. 

We have been advised of a provisional rescheduled date of 8pm Thursday
24th August until 06:45am Friday 25th August 2017. But those dates have
not been confirmed.

Our apologies for the inconvenience this will have. These changes are
outside of our control and we will try to keep you updated as best we
can.

Regards

Sean
