I just want to add one thing again, what some smaller providers have done is hire an IT MSP on a retainer basis for break/fix standby. They will pay $X for 5-10 hour blocks of time, and when the poop hits the fan the IT team will dispatch down to the DC to do the work which has already been paid for. Then you simply make this on site IT support a line item in your budget. This may be cheaper than remote hands in some facilities too depending on where you live or where the equipment is.
