Scheduled

IT Services will be performing a Node-B and Node-M Core Router IOS upgrade to address bugs during two distinct maintenance windows.

IMPACT : The secondary network path for inbound/outbound network connectivity will be taken down briefly (due to Dual Supervisors), while the primary path through Node-M will remain active. Certain customers who have VLANs spanned to/from campus locations to data centers at SDSC and TPCS will experience a brief interruption of service during this window. Some voice services would be affected as well.
