A nationwide broadband fault forced the Salvation Army in Whangarei to resort to manual recordkeeping for most of Tuesday.
Fortunately, services at the Sallies' Aubrey St office returned to normal yesterday but some Telecom customers were still experiencing issues with their internet.
The faults appeared to have been triggered by a software patch to one its computer servers in Auckland - but it affected customers throughout the country.
About two-thirds of customers were unable to use broadband between 1am and 8.45am on Tuesday and then between 9.45pm and 11.35pm.
Salvation Army director of community ministries Pete Mullenger said his staff were unable to access data on Tuesday but, unusually, the glitch affected only some computers. Telecom spokeswoman Lucy Jackson could not say how many Northland customers were affected as the issues experienced were intermittent, with connections dropping out for a time.
