MONITORING

PACE and the CEDAR vendor have identified and begun implementing measures to create additional capacity on CEDAR. More capacity is expected to become available Sunday evening as automated cleanup processes continue to run. We have verified that storage space is beginning to be reclaimed and will continue to closely monitor capacity utilization and system performance as these cleanup activities progress. At this time, these actions are expected to reduce pressure on the system and improve performance for affected users. As a precaution, users should continue to avoid creating, modifying, or transferring large amounts of data unless necessary. Read-only operations remain safe to perform. Additional updates will be provided as more information becomes available

MONITORING

We are closely monitoring storage capacity for the CEDAR service, which is approaching its available limits. A capacity expansion is planned for mid-October, but usage is expected to continue increasing before that work is completed. At this time, a small number of users have reported delays when accessing or updating data. Based on current performance trends, additional users may begin to experience similar issues. OIT is working with the vendor to identify options for recovering capacity and reducing the risk of service degradation. We are also requesting that users avoid creating, modifying, or transferring large amounts of data unless necessary to help preserve service stability. Users should not delete data at this time. Impact: Users may experience slower-than-normal performance when accessing, updating, or storing data in CEDAR."

MONITORING

Dear CEDAR users, The CEDAR storage system is approaching capacity. The addition of 2.4 PB of new storage is expected by mid-October. When possible, please temporarily stop writing and modifying data to CEDAR while mitigations are implemented. Users should not delete data – pausing writing and modifying data while work is carried out with the vendor is sufficient. Read-only operations are safe to continue. Thank you for helping us keep CEDAR’s performance optimal. Please contact us at pace-support@oit.gatech.edu with questions. We will follow up with additional details on CEDAR’s expansion once they are available. Thank you, The PACE Team

Description

OIT Network Engineering will be performing network maintenance on Saturday, September 26, from 6:00 a.m. to 12:00 p.m. Eastern. The work includes upgrades to network authentication infrastructure and supporting systems. During portions of the maintenance window, users may experience brief delays when initiating new network connections on eduroam, GTother, GTvisitor, Wired LAWN, DVLAN-enabled ports, and while roaming to eduroam at other institutions. Existing network connections are expected to remain active and unaffected. * Load Balancer Software Upgrade (CHG0037977) A software upgrade will be performed on the load balancers that support LAWN Authentication, Network Access Control, the Network Services API, the LAWN Portal, and several internal applications. During the upgrade, two brief service interruptions of approximately one minute each are expected as traffic transitions between appliances. During these interruptions, new network authentications and access to load-balanced services may be temporarily unavailable. Existing authenticated sessions will not be affected. * Network Access Control Platform Software Upgrade (CHG0037975) A software upgrade will be performed on the campus Network Access Control (NAC) platform. During the maintenance, users initiating new connections on LAWN networks (eduroam, GTother, GTvisitor, and Wired LAWN), DVLAN-enabled network ports, or eduroam services at participating institutions may experience brief authentication delays of up to two minutes. * Wired Network Authentication Server Migration (CHG0037976) The backend authentication service for Wired LAWN and DVLAN-enabled network ports will be migrated to new infrastructure. Users initiating new wired network connections during the migration may experience brief authentication delays of up to two minutes. ====== Up-to-date progress will be provided on Georgia Tech’s IT Service Status page, http://status.gatech.edu. After the maintenance is complete, individual users may visit http://services.gatech.edu to report any issues believed to be related to this maintenance. Campus IT staff who need to report time sensitive issues affecting multiple people and/or departments and require more immediate assistance should also contact OIT’s Infrastructure Operations Center at 404-894-4NOC (4662).

Description

Microsoft is retiring the 'memberOf' dynamic membership rule operator on November 3, 2026. A number of GT departments rely on this functionality to dynamically populate Microsoft 365 Groups and Microsoft Teams. The OIT Business Solutions team will be implementing new automation to replace this functionality during this maintenance window. No action is needed by customers, but impacted customers' CSRs/IT staff have been notified of this change (CHG0037944).
