Filtering issue with Google searches

We are aware of an issue on SSL Filtering where websites are getting blocked while being accessed through a Google search. This has been escalated within RM and their senior engineers are investigating this as a high priority.

Transparent filtering on your 172.* network

We are pleased to announce that new functionality is available whereby transparent filtering can now be deployed on your 172.* network. Schools will not see any additional charges for this new functionality.

New NAT IP address range

Collectively we have exhausted the subnet  that RM have previously set aside for NATs:  RM have now provided us with this additional range:

Please note that these IPs will only be used by RM when creating firewall rules on behalf of HICS schools – and not for their ‘core customers’. Further information can be found here:

Thanks for your ongoing support and if I do not post again before Christmas, I hope you all have nice break.


The HICS Team


One minute drop out this morning

Between 11:44 and 11:45 this morning, there was a loss of service affecting most of the schools on the network. This was due to a backhaul network issue within the Talk Talk Business infrastructure. This would have impacted voice and data services for lots of Talk Talk Business customers – not just Hertfordshire Schools. This issue occurred due to a ‘flap’ on a Talk Talk circuit which connects back to the Telehouse West site. Hopefully that’s our network wide outage out of the way for the academic year!

HICS Case Study

Herts for Learning has put together the following case study to illustrate the impact of the implementation of the new HICS service, in delivering both a tailored service and savings to schools:
