Updates Summary


Time Resolved: 18-July-2020, 8:45 AM UTC

Between 07:50 and approximately 08:45 UTC on 18 Jul 2020, the Microsoft Azure DNS service experienced a transient resolution issue which impacted connectivity for some dependent Azure services. Microsoft engineers restarted the Azure DNS service in several Azure regions. For most regions this was an impactless, or low impact, event; for a small number of regions the restart required a re-sync with the Azure databases which caused the restart to take more time. Authoritative and other DNS services were not impacted by this issue. The DNS service was fully mitigated at 08:45 UTC by the Microsoft Azure team, but some services with multiple dependencies may have taken longer for all customer to see full service restoration. Sitecore Managed Cloud customers using Solr hosted by SearchStax may have received notifications due to this DNS issue because one of the two methods SearchStax uses for availability monitoring relies on Azure DNS for communication. The other method SearchStax uses for monitoring remained operational and confirms no actual Solr service downtime or loss of data was registered during this period. These notifications were false positives and SearchStax has verified all services are fully operational at this time.
