Description:
As of September 2024, Cyber Security has issued new mandates around RHIC mail that affects all users. This announcement outlines the new requirements.

Effective September 26, the SMTP port will be blocked from use outside of the campus. Users will need to either connect through VPN or will need a separate SSH tunnel to send mail through the RHIC SMTP port. More information is available at https://www.sdcc.bnl.gov/services/email-services/email-client-configura…

The new requirements also mandate that any new or updated email password must be at least 16 characters long. Users whose email passwords don't currently comply with existing requirements will be contacted to change their passwords, which will need to meet this new 16-character mandate.

Network

Affected Area:
All SDCC services

Expected Impact:
No access to SDCC services during downtime

Maintenance Type:
Planned Maintenance/Downtime

Description:
This extended downtime is necessary for two key activities: upgrading user home directories beginning on Monday (for all programs but the NSLS) and a network maintenance scheduled for Tuesday (affecting all customers). This maintenance marks the final phase of the multi-year migration of SDCC services to a new data center.

Impact on Services:
- Storage and Data Transfer Services: Access will be suspended starting Monday, December 18th, at 5 PM EST to allow for a clone of the user’s home directories. Special Note for NSLS Program Users: The NFS home directory work scheduled from Monday to Tuesday does not impact the NSLS program. NSLS program users should expect regular operation during this period (until the network maintenance begins on Tuesday).
- Computing Resources: Access to computing resources (interactive and batch), storage services (disk and tape), and collaborative tools (BNLBox, RCF email, MatterMost, web services) will be unavailable throughout the respective maintenance periods.
- Batch Job Scheduling: Scheduling of new HTCondor and Slurm batch jobs will cease on Friday, December 15th, at 11 PM EST. Any remaining HTCondor jobs will be terminated on Monday, December 18th, at 3 PM.
- Interactive Sessions: Open sessions through the facility SSH gateways will be terminated at 5 PM on December 18th to facilitate the cloning/copying of user home directories.
- Email Services: The @bnl.gov email services may experience interruptions. Alternatively, users are encouraged to use the sdcc-staff-l@lists.bnl.gov mailing list to contact SDCC staff.
- NX Service and SSH Gateway: The NX service and SSH Gateway will be unavailable. Existing cssh sessions initiated before the outage will continue to function.

Restoration of Services:
Complete restoration of services is anticipated by 9 PM EST on December 19th. The SDCC will notify the community through its regular mailing lists.
We apologize for the inconvenience this may cause and thank you for your understanding and cooperation as we complete this essential upgrade to our infrastructure.

Maintenance Type:
Planned Maintenance/Downtime

Description:
On Tuesday, December 19th, from 6:30 am EST to 9 pm EST, network connectivity (both WAN and Campus) to/from the SDCC Facility and Science DMZ
will be unavailable due to scheduled maintenance.

This event marks the final phase of the years-long migration of SDCC services from the old data center to the new one. We anticipate the full restoration of
network connectivity by 9 pm EST on December 19th, concluding the outage. During the intervention period, access to SDCC services, including computing
resources (both interactive and batch), storage services (disk and tape), and collaborative tools (such as BNLBox, RCF email, MatterMost, and web services),
will not be available.

To prepare for this network outage, the scheduling of new HTCondor and Slurm batch jobs will cease on Friday, December 15th, at 11 pm EST. This pause
will facilitate the smooth draining and graceful termination of ongoing computing jobs. In addition, access to storage and data transfer services will be
temporarily halted on Monday, December 18th, at 5 pm EST.

This outage does not affect BNL mail service (@bnl.gov domain), which will be available during this period.

The SDCC will notify the community about the full restoration of services through its regular mailing lists.
