>We apologise to our customers for the service outage on Janury 18th between 22:30 and 23:30.
The cause of the problem was a fault optic converter on our main network link.This piece of HW caused a faulty one-way only communication, which resulted in Spanning Tree Protocol automated optimal route recalculation. This process of optimal route calculation was again and again disrupted by the mis-function of the faulty working HW link.
Because of the rather spooky behaviour of the HW element an easy and straithforward identification of the source of poblem was impossible. It took about 30 minutes to pin down the faulty element and consequently the network was back in order shorty.
We are very sorry for any inconvenience implied on our precious customers by this unfortunate and extraordinary event.
