On 16 August, we will be upgrading the main firewalls at Whiteknights. Unfortunately, we are unable to perform this as an ‘in-line’ upgrade, so the internet connection will be subject to a series of interruptions over a period of several hours starting from 6pm.
Due to the importance of these pieces of equipment for internet access from the Whiteknights Campus, this change has been tested thoroughly in our security lab over a number of weeks. We will also have assistance on site from our network infrastructure support contractor, should there be any further issues.
As the new devices do not run the same operating system as our current ones, we will need a few days to migrate the configuration. Unfortunately this means we will not be processing user-requested changes to the border firewall policies between 10 and 16 August, except in the event of a security incident.
As such, please could you ensure any firewall policy changes you need made are submitted before midday on Tuesday 9 August.
This affects the campus border firewall only, so changes to access for corporate applications, BMS, and CCTV systems will still be handled as normal.
