I received a lot of mails with questions about the fact that SP1 for SharePoint 2013 is currently not available for download and about April 2014 CU for SharePoint 2013. So I'm trying to answer all of them here in this blog post.
Q: I tried to download SP1 but noticed that the link from your blog to download center is dead. What's going on?
A: The answer can be found in the SP1 KB articles: 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.
Q: I have already installed SP1 - what does this mean to my systems?
A: First of all: NO WORRIES! As outlined in Bill Baers blog post there will be a patch to resolve the problem that prevents installing CUs and PUs on top of SP1. Currently there is no action for you aside monitoring my blog and other more official resources for further updates on this issue.
Q: I have planned to deploy SP1 and already downloaded it, before it got pulled. What should I do?
A: As outlined in Bill Baers blog post it is recommended to wait for the updated SP1 packages rather than replying the packages which got pulled.
Q: If there will be a patch, why has SP1 be pulled in the first place?
A: As outlined in the KB articles for SP1 an updated service pack package will be released which will not have the issue.
Q: Are the SharePoint with SP1 included packages (also known as "slipstream") also affected?
A: No, these packages are not affected
Q: Does the problem cause any harm - aside not being able to install future fixes on top of SP1?
A: No. It is only an issue with the patch installations. That's also the reason why the "slipstream" builds are not affected.
Q: What about April 2014 CU for SP 2013? I noticed it has been released yesterday and found a couple of fixes for SP2013 but no announcement on your blog.
A: Due to the issues with the SP1 installations most of the fixes planned for April CU have been postponed. The fixes you found are individual fixes for some components around SharePoint (e.g. FIM, Word Services,...). The so called "server" packages or "uber" packages were not released. We always recommend to install the server packages (these are the packages I announce in my CU blog posts). I will post an update as soon as more information is available.
