Recently installed update cache and message relay to new server through Sophos Central. After installation, I removed the Update Cache and Message Relay from the previous server. All of our devices' update source and message relay source did not change to the new server - it is now updating directly from Sophos through our Proxy, which causes network congestion. Please note that the changes mentioned above was made 3 days ago and would have expected the changes would take effect on our devices.
