Phone company O2 is still working to solve issues caused by the fire at the JBJ Business Park, which has left customers across Northampton without internet access for almost a week.
The blaze took hold in buildings next to the Blisworth Exchange, which caused internet access to be interrupted late last Friday morning.
The problems were still not fixed yesterday, and there was no timescale on when access would be restored.
O2, which supplies broadband from the exchange, said the fire had caused issues in Weston Favell, Towcester, Moulton, Kingsthorpe, Hardingstone, Duston, Daventry and Chapel Brampton.
Further afield, it caused problems in and around Kettering, Corby, Wellingborough and Rushden.
It has also created issues for some businesses, as card payments cannot be taken on chip-and-pin machines while the internet is down.
O2 initially said it had not been able to get on the site due to it remaining under the control of the fire brigade.
A spokesman for the company said: “We have found an alternative solution and we are working with our suppliers to get back up and running.
“We are re-routing traffic to an existing data centre, which does involve a large amount of work.
“We are not able to confirm a timescale at this stage, but we are working as quickly as possible.
“It is a priority for us to get our customers back online.”
Alistair Rumbold, aged 53, of Upper Harlestone, was one of the O2 customers who lost internet access.
He said: “There has been no communication from them to us. I have been ringing them every time to get the information.
“It is so frustrating, I’m having to do the donkey work.”
Hannah Green, a supervisor at the Old White Hart pub, in Far Cotton, said the disruption had also caused problems for the business.
She said: “We’ve had to turn a few people away because we can’t take card payments.
“We had a call to say they would try to get us sorted by Tuesday, but it’s still down.
“We’re lucky we’ve got a cash machine in the pub.”
Mark Cotton also wrote on Twitter: “The o2 broadband outage is killing Northampton business. Still no help from them. Six days now.”
