At 16:10 UTC on April 25th Bitly's backup system protecting click and scan functionality automatically engaged and our on-call Engineering team was alerted to errors within our website and API including impact to the ability to create new links.
By 16:28 UTC we had identified the root cause as an issue affecting internal load balancing with our cloud hosting service provider (details on this incident can be found on their status page).

Our Engineering team worked directly with the service provider and took necesary steps to restore service once the service provider mitigated the incident. Once the cloud load balancers were back online, access to our website and public API was quickly restored; by 17:31 UTC our production systems were fully functional.

We sincerely apologize to our customers who were impacted during this disruption.
