The Metropolitan Police Service is still trying to get to the bottom of the outage that prevented staff accessing some IT services nearly a month after it first emerged.
The "major network issue" surfaced on 9 June preventing coppers from accessing a number of ICT services including printer services and systems access for MPS staff and officers.
A spokesman at MPS claimed the "vast majority" of problems have been resolved with "almost all" staffers now able to use systems normally.
"A small number of print services are still affected, but staff and officers continue to be able to print on the back-up servers so it is not service-affecting," he told The Register.
The MPS had recently acquired a fleet of Canon printing devices and it was thought their addition to the existing infrastructure could be part of the problem, but this has now been discounted, said the spokesman.
"[The] Canon print devices have undergone a series of rigorous security checks before being allowed onto the MPS network. The current issues are considered to be entirely unrelated to the introduction of these devices onto our infrastructure."
Despite this, the gremlins that caused the network glitches have yet to have their collar felt by IT enforcement managers working at MPS.
"Whilst we understand the issue, due to its complexity, investigation will continue into its root cause. We cannot provide further detail until this work in complete," the MPS spokesman revealed. ®
