This evening at 4:55pm CDT in our H1 data center, electrical gear shorted, creating an explosion and fire that knocked down three walls surrounding our electrical equipment room. Thankfully, no one was injured. In addition, no customer servers were damaged or lost.
We have just been allowed into the building to physically inspect the damage. Early indications are that the short was in a high-volume wire conduit. We were not allowed to activate our backup generator plan based on instructions from the fire department.
