   Web page “New and improved features in SharePoint Server Subscription Edition 26H1 release” is missing. It does not exist.

   hi Stefan
   Will there be a KB release on 14th July for SharePoint 2016 which is end of support date, or is June 2016 is the last one?
   THanks

      Hi Ramen,
      there will most likely be one final CU on July 14th.
      Cheers,
      Stefan

   I installed the June 2026 CU on 14 SharePoint farms. I have experienced the same two issues as last month. Sometimes the issues appeared a few days later, after Windows Updates were installed. Windows Servers was restarted after each update.

   1️⃣ So far 9 farms had Search Service Application either in error state or remained in “Paused for:External request”.
   ➡️After restarting the “SharePoint Search Host Controller” and waiting about a minute, Search worked again. On two farms I had to do this twice.

   2️⃣ On 1 farm the SharePoint Website response time changed from 0.3 seconds to exactly 80 seconds (which resulted in some timeouts). The issue occurred after latest Windows Updates were installed.
   ➡️ After running PSConfig again, the issue was resolved. PSConfig already ran successfully a few days ago.

   Hope this helps someone else.

   Cheers from 🇨🇭,
   Benjamin
