On 01/09/2017 and 01/10/2017, we experienced a degradation in performance on one of our Apache Solr servers. We were able to remediate the issue for most customers impacted within 30 minutes. During this time, the impacted customers who rely on Apache Solr to provide robust search capability found that capability diminished.
Apache Solr is a powerful service that Pantheon has been able to reliably offer its customers with the most content rich sites. We are working to increase the speed with which we can remediate this particular failure in the future. Additionally, we will look into ways to further reduce the occurrence of these sorts of incidents.
We apologize for any inconvenience caused by this incident.
