Search and Data Export Issues – 1/26/15 10:13 AM PST

We are experiencing issues with one of our backend services which will mean that for a subset of Yammer networks and their users, their search experience will be lagging. This means that new data within the last 9 days will not be readily searchable but data older than approx 9 days  should be searchable.  If those networks use the Data Export capability then this will not work either.

Our engineers investigated a problem that was affecting a large subset of our users where the main page would appear but feeds would not load. This incident began at 09:00:36am, PST and ended at 10:00:36am, PST.

Due to a unique set of environment circumstances the feed loading problem did not appear for our teams internally, which significantly delayed discovery of the issue and resolution of the service interruption. Once the customer reports reached the engineering team the interruption was quickly investigated and resolved.

The engineering team are reviewing the systems responsible for monitoring these conditions and adjusted our process so that our internal environments will enable more immediate discovery of feed issues that affect our external customers.
