I think this deserves a short blog post of its own, just in case you are (like me!) in the midst of deploying a production farm with SP 1 into the wild.

Microsoft just announced the following information on their SP 1 page:

[blockquote]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.[/blockquote]

So this is some pretty heavy information. Not to say the least since everyone (Microsoft included) promoted SP1 as a top requirement to install in your SharePoint 2013 farms. With that said, shit happens, I understand. However I just wanted you to know that you might want to hold on for a while until they’ve found a fix for people who currently are deployed with SP1 or fixed a new installation package for SP1.

All the details can be found here: http://support.microsoft.com/kb/2817429/en-us

Update 1!

As per a conversation with Bill Baer from Microsoft, there’s now additional info available. And I quote:

Slipstreams not affected!

[blockquote]P.S. Just received confirmation that the slipstream builds are not affected.[/blockquote]

A fix for customers who have already deployed is in progress!

[blockquote]For existing customers who have deployed Service Pack 1 we’ll have an update available (ETA TBD) that resolves the issue.[/blockquote]

With that additional info, I (and my clients) can feel a bit more relaxed.

Update 2 – April 22nd!

I just got word that Bill posted an update about the issues with Service Pack 1 for SharePoint 2013.

Check his post out. To quote the most important parts:

**Customers with Service Pack 1 Deployed
** For customers who have previously deployed Service Pack 1, download the updated Service Pack 1 and install over the existing Service Pack 1 running PSConfig or PSConfigUI immediately following.
**Customers without Service Pack 1
** For customers without Service Pack 1 deployed, download the updated Service Pack 1 package and deploy as per the KB documentation.

So this is great news. We don’t need a separate fix to close the gap, we just download and install the newly released bits on top of the old ones and run psconfig – voila.

Thank you Microsoft for the rather quick resolution, and for being honest and public about the issues at hand. You rock, Bill.
