Mr Henshaw Ogubike, director of information in the Office of Accountant-General of the Federation (OAGF) said on Friday in Abuja.
GIFMIS is an IT-based system for budget management and accounting.
It is meant to improve Public Expenditure Management processes, enhance greater accountability and transparency.
Ogubike said the shutdown of the GIFMIS platform was caused by the fire at the Treasury House on Wednesday.
The fire affected the outdoor panels of the cooling system to the server room.
The server automatically shut down itself, denying service on the GIFMIS platform.
“Service has been restored and payments can be made and received through the GIFMIS Platform,’’ Ogubike added.
He expressed the regrets of OAGF regarding any inconveniences the shutdown might have caused.
