N4L are committed to improving network security on the managed network. As such today (28th April) we implemented a change on school routers to add further security to the network and your email sevices. We do not anticipate this change having any noticeable impact to your internet or email service. However should you notice any impact to your managed network performance or to your email service please contact us on 0800 532 764 (M-F, 8am-5pm) or email us at [email protected].
