I guess I can share the internal email from them now as this issue is fully public.

network due to a major fire incident in a building (BTSOL - 4th Dimension
Mind Space, 4th floor Link Road, Mumbai, Maharashtra) in which Bharti POP is
located .The building has been evacuated and presently nobody is
being permitted to go inside the building. Because of the fire incident,
power has been completely switched off for the entire building.Due to
