Our building is located approx. 100 meters from the explosive charges. They happen several times per day, and really shake the entire building a lot. This is going to go on for many days and the blasts are supposed to get stronger.

Our server rooms are nothing fancy; one of them has all the racks on hard concrete while the other one has a raised floor (the one which allows the cables to go beneath it).

Does anyone have any tips, countermeasures or best practices for us?

Currently we are thinking of the following countermeasures:

• Daily report of the server rooms status lights (HD lights, power supplies and so on).
• Nightly check disk scan on the most important servers
• Order in extra supply of spare harddrives
