This page is being served from an S3 bucket in the eu-west-1 region via a CloudFront
distribution. Route 53 continuously checks the health of this endpoint; if it fails, DNS will
automatically redirect all traffic to the DR region in us-east-1 (North Virginia).
TerraSignal is a Search and Rescue GPS coordination platform designed for Irish mountain rescue teams. Field Raspberry Pi devices operate offline during active searches; this cloud console is used by sector managers (JUSMs) to review historical operations and coordinate multiple units across a geographic sector. 24/7 availability is required because rescue operations can be initiated at any hour, in any weather, from anywhere in the country.
The deployment uses Amazon RDS (PostgreSQL) for persistent storage, Amazon SQS for asynchronous sync ingestion from field devices, AWS KMS for encryption at rest, Amazon CloudFront for low-latency content delivery, and Amazon Route 53 with health-checked failover for cross-regional disaster recovery. All infrastructure is defined as code via AWS CloudFormation.
