Pages 3 – 4 of the Changes to UCAS link systems technical guide have been updated to reflect this.
These ranges have been expanded because our infrastructure supplier (Amazon Web Services) has increased the number of addresses it uses. The ranges are used by all of the odbc-link services we deliver – both production and test.
We’re continuing to work with Amazon on the changes required to our architecture to remove the need to add these ranges to your firewall.
We’re sharing this information with your technical team, but please forward it to anyone else in your organisation who needs to know. If you have any questions, please contact our HEP Team on 0344 984 1111, or at hep_team@ucas.ac.uk.
