An article in The Register [1] says it wasn't a fire, but speculates: While we lack any evidence on which to base an assertion, The Register has reported on erupting UPSes and tiny puffs of smoke leading to hypoxic gas being released into data centres. The whole point of hypoxic gas release into data centres is to deprive fires of oxygen. And as humans need oxygen, it can be a while before engineers can return to a data centre. The Register mentions this as it fits the facts offered in this incident, and with AWS’s language about “environmental conditions” preventing entry. The Register says that it'll update its article if it gets further info.
