On February 1st (like on January 27th), we faced a performance issue that affected our Apps and Dashboard loading time, due to a high load on our main in-memory database.

This load was due to an old component responsible of the contacts loading in our product. From 14:28 UTC to 15:08 UTC, these slowdowns were too important and they prevented some of our users to refresh their Apps and Dashboard.

Thanks to the improvements we made on our infrastructure last June, call routings were not impacted.

Short term action was to limit contact loading for old Apps still using this component. For the past few weeks, we worked on our new Phone App used now by all our Mac & Windows users and which doesn't require this broken component.

We are also working on a new architecture for Apps and Dashboard loading that avoid such dependencies between components. We’ll start to deploy this month in order to continue to deliver the highest reliability our customers expect from their phone system.
