+## Device facing DNS updates
+
+On Monday, 2024-07-22 at 15:00 UTC Foundries.io team will be performing an
+update to the IPv4 addresses for the device-gateway and EST services. The
+current IPv4 addresses will be left running for 60 days to provide adequate
+time for devices to pick up the DNS change.
+
+The changes will be:
+
+| Service        | Current       | New           |
+| -------------- | ------------- | ------------- |
+| device-gateway | 35.226.43.150 | 34.171.143.59 |
+| EST server     | 34.173.97.119 | 35.202.202.20 |
