What Happened

On March 29, 2024, at 07:23 UTC, a large increase in incoming connections to the uk-1.platform.sh region caused the gateways to become unresponsive. Availability of sites/environments in the region was impacted.
This incident did not affect Dedicated clusters.

Customer Impact

Grid projects on the uk-1.platform.sh region were affected, resulting in temporary outages and reduced performance for customer sites. Sites availability and performance was shortly degraded.

What Was Done to Resolve the Incident

To address the issue, our engineers initially blocked the majority of the malicious (DDoS) traffic at the time and made various configuration and software changes in our internal gateway systems to handle these situations better.
They continued monitoring the changes to ensure system stability and performance.
