[Update – March 25, 2021 – 3:07pm] 

This is a follow up to yesterday’s message about the campus network connectivity issues that impacted PACE.  By 3:24pm yesterday, OIT’s network team was able to rapidly resolve the connectivity issues, which was quickly updated on the status page link that was provided earlier.   Analysis of the incident, which was made available to us at a later point, revealed that the issue was identified to be a network spanned into the Coda data center from the Rich building that experienced a spanning tree issue (a network loop).   This caused a cascade of issues  with core network equipment due to specific failure scenario that caused widespread connectivity issues across the campus.  OIT’s network team resolved the issue with the affected network that resolved the other connectivity issues affecting the campus.   OIT’s network team will conduct further investigation regarding this to prevent future occurrence.

Since yesterday at about 3:30pm, all PACE users should have been able to access PACE managed resources without issues.  There was no impact to running jobs unless they required external resources (outside of PACE).   If you have any questions or concerns, please direct them to pace-support@oit.gatech.edu

Dear PACE Users,

At around 2:30pm, OIT’s network team reported connectivity issues. This may impact users’ ability to connect to PACE managed resources at Coda, such as Phoenix, Hive, Firebird, PACE-ICE, CoC-ICE and Testflight-Coda. Currently, the source of the problem is being investigated, but at this time, there is no impact to running jobs unless they require external resources (i.e., from the Web). We will provide further information as it’s available.

Please refer to the OIT’s status page for the developments on this issue: https://status.gatech.edu/pages/incident/5be9af0e5638b904c2030699/605b8495e2838505358d3af3

If you have any questions or concerns, please don’t hesitate to contact us at pace-support@oit.gatech.edu

We apologize for this inconvenience.

Best,

The PACE Team
