Users have been experiencing some failures today due to hash value mismatches.
Some packages have became corrupt when they were copied to distro6 to spread the load across the system. This only affects a task sequence if the package chooses to download form distro 6 instead of distro 2 so it can appear to be intermittent.
We are currently trying to identify these packages and redistribute them. Unfortunately this may take some time.
Please ensure that your task sequences were successful via the SCCM task sequence reports and let us know so we can fix it for you.
We will keep you up to date via this blog.
