Over the summer holiday period embc and KCOM are upgrading the firewalls and associated technology used to manage the embc service. As such there will be possible downtime during the period Friday 24th July and Saturday 8th August. This timing avoids the exam results period and with changes scheduled after 22:00 reduces as much as possible, any potential impact to schools and local authorities.
For more detailed technical information on the embc KCOM Firewall Summer Upgrade please see the Summer Upgrade documents in the KCOM Document store on their portal https://portal.kcom.com/documents/ using your username and password to access.
