Microsoft has confirmed in a blog post on the Feedback Hub that the Insiders in the Fast Rings will not be getting any new Insider Preview Builds until the start of Next week. The reason behind the delay in release of New Preview builds was posted on the Feedback Hub.
“We are performing some upgrades this week to our services that are used to approve and monitor builds from the Development Branch to our Windows Insiders. Once the upgrade is complete, just as we flight the OS through the rings, we will be flighting the service upgrades through the internal rings first.”
So if you are a Windows Insider in Fast Ring Redstone 2, then you would need to wait until the start of next week for getting access to new preview builds to try any new features released by the company.
The Current Development Branch is stuck at the last released build 14915 which was released last week. The company also revealed that the Insiders who are planning to setting up a new device or trying to change ring will not be receiving any new available build for that ring until the upgrade process is completed.
Hence if any of you are on Fast/Slow or Release Preview make sure to stay on the current Ring and not try to shift to any other Ring until next week for you to test the new build released by the company.
