Estimated timeframe : 14:45-17:00
Actual timeframe : 15:05-16:30
Reinstate full resiliency of the network core stack, after a decreased resiliency caused by a stack member switch dropout in the iGent datacenter facility following yesterday's firmware upgrade.
16:28 core stack has been reconfigured from 4 to 3 stack members ; as network bandwidth has been architecturally overcommitted, no detrimental network performance is expected. Vendor will be contacted for remediation.
16:22 stack fiber wiring from 4 to 3 members to (temporarily) restore resiliency.
16:17 boot loader diagnosis reveals issues with internal NAND storage ; vendor intervention required.
Estimated timeframe : 15:00-17:00
Actual timeframe : 14:59-17:40
Upgrade Core and selected network switches to the latest firmware
17:16 The network core stack consists of 4 switch members, to ascertain both bandwidth and resiliency. After the upgrade, one switch member (colocated in the iGent DC facility) has dropped out of the stack, decreasing resiliency ; this will be further investigated.
17:12 All targeted switches have been upgraded and are fully operational.
