If you have logged in to Digimap recently you will be aware that the service, particularly the Ordnance Survey Collection, is suffering from performance issues. The biggest factor in this is the sheer number of users accessing the service during core hours.
The beginning of the autumn term is the busiest period for Digimap, while new users register and new courses get underway. This year the number of users registering for Digimap is exceptionally high, in the light of the changes to access and authentication systems which occurred in August. This means that a significant proportion of returning users are required to re-register using their new login credentials.
While significant work is underway to improve the performance of Digimap, there is no immediate solution. If you are having trouble using Digimap, please try again at a time when the service is less busy. Quieter periods are early in the mornings and later in the evenings. The busiest time is usually during weekday afternoons.
