Woensdagavond is de stroom opnieuw uitgevallen in het Scarlet datacentrum in Vilvoorde. Uit een uitgebreid statusoverzicht dat door de Belgische hoster Easyhost is bijgehouden blijkt dat de stroomstoring om 19:20 uur begon en tot 21:31 uur duurde.
In een verklaring van Scarlet staat te lezen dat de stroomstoring veroorzaakt is door dat de UPS-systeem van het datacentrum het opnieuw lieten afweten. Zaterdagavond was er al een stroomstoring in het Scarlet datacentrum. Om er voor te zorgen dat dit probleem zich in de toekomst niet meer voor zou doen is men meteen begonnen om een tweede UPS-systeem te installeren. Echter nog voor dat het UPS-systeem in gebruik kon worden genomen liet het huidige UPS-systeem het opnieuw afweten. Dit keer met een stroomstoring die ruim 2 uur duurde tot gevolg.
De officiële reactie van Scarlet:
First of all we would like to apologize for the inconveniences caused further to this night power outage, the second in less than 1 week. We would like to inform you on the chain of events, the actions
undertaken so far and the future plans:Last Saturday, 25/04/2009 at 20:55h, the Scarlet datacenter in Vilvoorde experienced a power-outage. Commercial power to the Scarlet datacenter was interrupted as a result of a traffic accident.
Since the Scarlet datacenter is equipped with a backup-power infrastructure, automatic switch-over to this backup-power was initiated. However, because of a failure in the logic controlling this, switch-over did not occur as designed and the power to the server rooms was interrupted. All Scarlet- and customer-systems housed in this infrastructure became unavailable.A specialized engineering-team was sent on-site and backup-power was switched on manually after 12 minutes. Major part of the Scarlet-services were restored after approximately 15 minutes.
Some services however experienced problems till Sunday afternoon. Briefly after the incident, the supplier of the backup-power systems has gone on site to investigate the problem in depth. Only a couple of weeks earlier, they had performed a satisfactory routine-maintenance on the system. The Scarlet datacenter was running on backup-power while the supplier was planning a complete overhaul on the primary backup-system.To anticipate on this overhaul, Scarlet was planning to secure the primary backup-system by a secondary backup-system. Unfortunately, this night at 19h20, the primary backup-power failed before the secondary backup-system was operational. Currently, the datacenter is powered by commercial power, protected by the secondary backup-power which has been taken into service this evening.
Scarlet will keep you closely informed about the progress to completely restore the normal operational modus.
