** Description changed: Very slow throughput and occasional timeouts are observed when - provisioning new Ubuntu 24.04 ARM servers in AWS (ap-southeast-2 + provisioning new Ubuntu 24.04 T4g ARM servers in AWS (ap-southeast-2 region). The issue appears to affect connectivity to the following mirrors: - ap-southeast-2b.clouds.ports.ubuntu.com - ap-southeast-2a.clouds.ports.ubuntu.com - ports.ubuntu.com + Additional findings: + + - The issue is reproducible across multiple new and existing T4g ARM instances on Ubuntu 24.04 and Ubuntu 22.04 images + - On x86 instances in the same region, Ubuntu repositories resolve to ap-southeast-2.ec2.archive.ubuntu.com, and download performance is normal + Environment: - Platform: AWS EC2 - Region: ap-southeast-2 (Sydney) - - Instance type: t4g.small (ARM / aarch64) - - OS image: Ubuntu 24.04 default cloud image + - Instance type: T4g (ARM / aarch64) + - OS image: Ubuntu 24.04 / 20.04 default cloud image Observed behaviour: - Very low download throughput during apt update / package installation - Provisioning delays / timeouts - High latency and intermittent packet loss during ping tests Workaround: Switching to the AARNet mirror (mirror.aarnet.edu.au) significantly improves throughput and provisioning completes normally Additional notes: - This behaviour appears consistent across multiple newly provisioned and existing instances
