Update
NID verification is up and running according to Porichoy.
Deteriorated
Assalamualaikum,
A power system ‘hiccup’ at an office of Bangladesh Telecommunications Company Limited or BTCL in Dhaka has left around 30,000 government websites inaccessible.
This is the only reason why the NID verification is not working. We can only fix it when the government issue will be fixed.
