I agree with you. From my past experience any data center is subject to risks. I've witnessed:

  Power failures.
  Cross site links being cut due to engineering works.
  Over heating due to air conditioning failures.
  Flooding

And I've experienced all the above from a very large, very well known, very expensive data center company based in London.

This is true of every data center I've worked with. Also network providers: everyone has downtime and sometimes you learn the hard way that despite being written into your contract someone took the cheap way and ran your “redundant” fiber through the same conduit which a backhoe just tore up.
