Guernsey's government says it's run checks this morning following the global cybersecurity update that's taken out news broadcasters and affected airports and rail services.
A spokesperson for the States says checks have been made on all systems that rely on Microsoft.
There has been an impact on the Schools' Information Management System, known as SIMS, and Beau Sejour, which as of lunchtime on 19 July was still having problems processing card payments.
SIMS, says the spokesperson, has had most of its functionality restored.
Guernsey's port and airport have run smoothly throughout the period of disruption.
The States says it's been in touch with major island retailers and only one reported a problem taking card payments but that has been resolved.
Government says it will continue to monitor the situation.
