After several outages where we received pathetic root-cause reports initially, and had to push them hard to provide actual data, and clear commitments to shore up their systems, I would describe them as "fanatical liars".
It is funny, just the other day my wife and I were discussing cloud stuff and I said "I wonder whatever happened to Rackspace". Sounds like they've continued their path of sub-par strategy since I last dealt with them a decade ago.
