During the emergency reboot of ESXI02.R01 following our network monitoring advising the management interface was showing as off-line. We discovered an issue with the ARP timeout settings on LON01-CORE core that could have caused extended downtime in the event that the EasyBond service needed to flip between aggregators.
We have corrected this configuration issue and completed a fail-over test which completed as expected.
Users on EasyBond would have seen 2 x 30 seconds outages. We apologise for any inconvenience caused.
