Computers and free Internet will be offline in all Essex libraries tomorrow (September 21).

Essex County Council says an “essential upgrade” means the PCs and Wi-Fi will be unavailable all day.

The booking system at libraries, including those in Loughton and Epping, will also not be working.

Computers are normally available free for one hour, or two for jobseekers, and libraries have free Internet for those with their own devices.
