Digital keys not working due to outage on 3rd party end (Assa Abloy)

Incident Report for Mews

Postmortem

Problem

On 2026-06-11 at about 9am BST, a technical issue on our third-party partner Assa Abloy's (Vostio) side caused their API to become temporarily unavailable. This impacted digital key services for some Mews customers and their guests, meaning some key creation and key management operations may have failed during the outage window.

Action

Our team detected the issue through internal monitoring tools and immediately began investigating. We contacted Assa Abloy's technical team, who confirmed the issue was on their side. While waiting for their resolution, we monitored our systems and published a status update to keep customers informed. Assa Abloy deployed a fix at approx 9.10am BST, and we continued monitoring to confirm that services had returned to normal. The incident was fully resolved on 9:38am BST.

Causes

A technical issue occurred within Assa Abloy's infrastructure that affected their Vostio API. Since Mews relies on this API for digital key operations, the outage caused some key cutting requests to fail and prevented some reservation updates from being processed on the Vostio side. Assa Abloy has indicated they will publish a root cause analysis with further details.

Solutions

Assa Abloy's R&D team identified and deployed a fix for the underlying issue. On the Mews side, we are taking steps to improve our response to similar third-party outages in the future, including enhancing our monitoring to detect these failures faster and working with Assa Abloy to improve our visibility into the status of their services.
