KnowledgeTreeLive Document Management On-demand

Intermittent Back-end Amazon S3 Errors

Earlier today we experienced intermittent failures reading from, and writing to, the Amazon Simple Storage Service. This would have affected some account creations and the reading of writing of documents to KnowledgeTreeLive. KnowledgeTreeLive does attempt to retry writes to the S3 repository and, if it fails, will notify the user of the failed upload of a document.

It is understood that Amazon has resolved the issue and service has stabilized.

We experienced a temporary database connectivity issue. No loss of data occurred. Only one of our database servers was affected by this, and we were able to bring in another server that was on hot-standby.

We are putting additional safeguards in place to ensure that this does not happen again.
