Microsoft has just withdrawn its availability of Service Pack 1 for SharePoint 2013 with the following note:
Notice
We have recently uncovered an issue with this Service Pack 1 package that may prevent customers who have Service Pack 1 from deploying future public or cumulative updates. As a precautionary measure, we have deactivated the download page until a new package is published.
If you have downloaded SP1 but have not implemented it yet, we recommend waiting until there is a new version published as this one may cause issues.
