The authority is working closely with the experts at the National Cyber Security Centre to investigate the issue.
A council statement says: “While we investigate, some of our online services may be affected. We are aware for example that this is impacting some online forms and our planning applications.
“We are working to resolve this issue as soon as possible and we apologise for any inconvenience experienced at this time.
“It should be noted that the council’s IT services are not provided by Civica. Civica provides Revenues, Benefits, Debt collection and Customer Services processing functions on our behalf.”
The council’s live streaming service for its meetings is also currently unavailable,
Canterbury and Dover councils have also been affected by cyber attack incidents.
