    The yearly power downtime at our Holyoke data center, MGHPCC, has been scheduled by the facility. This year's power downtime will take place on Tuesday June  15th - 18th, 2025.  There will be no June monthly maintenance as a result.

    Since the facility will be powered down for two days this year, we will not be performing the usual maintenance tasks. 
    That said, networking and other key infrastructure will be doing maintenance.

    IMPORTANT NOTE: FASRC storage at both Holyoke and Boston will be affected and should not be expected to be available throughout the downtime. Please plan ahead accordingly.
