On Monday, May 4th at approximately 18:07 we experienced a network outage at our Oslo data center. This resulted in service disruption for all websites hosted on this data center.
With any significant event that affects our customers, we conduct an extensive examination to understand the root cause and develop a course of action to improve our systems and procedures. To that end, we wanted to provide a synopsis of the situation that occurred and our reassurance that we are working diligently to proactively mitigate and prevent future outages.
A microblad switch in our Oslo data center crashed causing internal network loops. Which, in turn, resulted in a partial failure outage for certain servers in our data center.
A large portion of the servers came back online automatically immediately. A small portion did not. We had identified the root of the issue at 18:28 and at 18:36 we had implemented a fix. At 19:18 the fix had allowed for all the servers to be back at full capacity.
We are in the process of modifying the current network architecture to prevent or reduce the impact of any device failure by improving our monitoring and failover triggering. We're doing this by adding additional core switches to considerably strengthen the network.
Outages disrupt your life and your business. We understand and we take our responsibility to you very seriously.
Please allow me to take this opportunity to thank you for your business and provide my personal assurance that we are dedicated to meeting our commitment to you.
