Kirklees Council’s website and phone lines have been put out of action by a power surge.
Many parts of the council’s website have been inaccessible since Boxing Day.
It has meant people looking for bin collection dates or office opening hours have been unable to find the information online.
A Kirklees Council spokeswoman said: “The council is currently dealing with a network problem that has significantly affected all our digital services, including our telephone lines.
"We are working hard to get the system up and running again and our priority is to get the phone system back online.
“The council’s teams are following their business continuity plan which is prepared in advance for situations like this. This includes reallocating and managing resources as required. Our priority is as always to ensure that we can operate services that keep children and adults safe.
"We will update our news site www.kirkleestogether.co.uk as and when we have more information.”
The Carephone Service which people can use to call for help if they suffer a fall or are taken ill is unaffected and working as normal.
