Full technical description from our CTO:
"On Thursday, November 19, at 3:40 AM, while running an automatic backup of our search index, the scripts hadn't finished the operation successfully. As a result, it corrupted metadata of the search index and invalidated backups. It didn't affect our parts or application data, which resides in a completely different part of the infrastructure, however, it hampered our ability to run application searches. Our engineering team quickly configured a new search cluster using pre-built schema and started a process of full indexing from the parts and application databases. Due to the volume of our catalog, the process took 8 hours to complete. However, we prioritized the most selling brands and the most purchased vehicle data first, giving our clients the ability to work with the catalog before the process was completed.
We understand the importance of our search capability to our clients and are working hard right now to analyze the outage and prevent this from happening in the future. We will ensure that the backup process is running smoothly and add additional infrastructure to our Beta server to ensure proper testing of the scripts and the operation workflows. We will also adjust our Production cluster and add more redundancy to the search index and related infrastructure."
