During an internal training exercise a “reload” command was issued to CORE01-LON instead of CORE01-HOR which resulted in a reboot of both the primary and secondary supervisor modules. This reload caused a 5 minute loss of service to LON01 for all directly connected services and customers.
Safe guards will be put in place on LON01 to prevent this happening again in such a scenario.
We apologise for any inconvenience caused.
