Live demo Grafana instance (grafana-lake.demo.devlake.io) is unreachable - all live demo links broken

[ewega]

Description

The hosted Grafana instance at grafana-lake.demo.devlake.io appears to be completely down. All "View live metrics on Grafana" links across the website return no response — the server is unreachable at every endpoint (root, /grafana/, /grafana/api/health, individual dashboard URLs).

Impact

This affects every live demo page on the website, as well as the homepage:

Live demo pages (under livedemo/):

• DORA — links to grafana-lake.demo.devlake.io/grafana/d/qNo8_0M4z/dora
• Engineering Overview
• Engineering Throughput and Cycle Time
• Weekly Bug Retro
• GitHub
• GitLab
• Jenkins
• Jira
• SonarQube
• Weekly Community Retro
• Community Experience

Homepage:

• The "Top Community Contributors" section in src/components/Team/Contributor.tsx embeds an iframe from grafana-lake.demo.devlake.io
• The "See Live Demo" link in src/components/Sections/WhyDevlake.tsx

DORA docs (all versions from v0.15 through Next):

• Each version's DORA.md links to the live demo Grafana instance

Current Behavior

Clicking any "View live metrics on Grafana" link results in a timeout / connection refused. The static screenshots (PNG) on each page still display, but the interactive Grafana links are all dead links.

Expected Behavior

The Grafana links should either:

1. Point to a working hosted Grafana instance with live data, or
2. Be removed/replaced with a note if the hosted instance is no longer maintained
