Our data centre survived a complete power outage
On the 2nd of January and 10:15 am the data centre we house the majority of our infrastructure in experienced a complete inbound power outage courtesy of EDF Energy. This was caused by a malfunctioning sub station about 1km away from the site. Our equipment was not affected at all, and we passed through the incident entirely protected by the excellent service at the data centre.
From the release sent out by 4D:
The UPS and generator at Sirius 2 took the load immediately and functioned correctly for the duration of the mains failure.
4D notified EDF immediately of the issue and an engineer was on-site within 10 minutes. Once the faulty substation that was causing the issue was identified, power was re-routed by EDF and Sirius 2 was back on the mains feed by 11:00am.
All backup systems functioned as expected resulting in zero power downtime for our clients. EDF have confirmed we are unlikely to experience any further outages as the issue has been properly identified and contained.
This is especially pleasing to see it working 🙂 The data centre runs a test of the UPS and generator back ups once a week regardless, but to actually see it used in anger and cope without an issue is comforting and we’re very pleased.
4D keep a minimum of 2 days of fuel for the generators on site at all times to handle outages like this. Combined with a mammoth UPS setup as well as running 2 entirely separate internal power grids with dual feeds into each rack, we remain entirely confident that ours and our clients equipment is protected.
