here's why:
contacted techs in the datacentre and they said the server isn't accessible
because the DC is experiencing the problem with power supply. Here is the exact
answer:
More information on the power failure:
- The building where our datacenter is located lost power.
- The UPS systems did function properly and carried the power load.
- The generators did start, however the transfer switch that moves load from
commercial power to generator power did not function properly.
- The UPS batteries were drained because the generator power could not be
transferred.
- The UPS system does not power the HVAC units, so the temperature inside the
datacenter climbed very quickly, forcing us to shut down ALL servers to prevent
heat from damaging hardware and data.
The generators and UPS systems are the responsibility of the building owners
which we are leasing space from, and they were tested and expected to work
properly. It has not yet been determined why the generator power was not
transferred properly.
