I have just prepared everything to have Helia running in/with our Tiros experiment to test website retrieval performance:

• Infrastructure changes: https://github.com/plprobelab/probelab-infra/pull/75
• Website changes: https://github.com/plprobelab/website/pull/80
• Website deploy preview: link
• For now, I have added Helia data only to this one graph: link (doesn’t show any helia data yet because we don’t have any)
• Updated Grafana Dashboard
