Problem to dispaly guidelines:

2023/11/08 09:11:07 [error] 39#39: *261330 connect() to [2606:50c0:8000::154]:443 failed (101: Network unreachable) while connecting to upstream, client: 10.244.9.63, server: , request: "GET /proxy-githubusercontent/C2DH/jdh-notebook/master/examples/hermeneutic-layer.ipynb HTTP/1.1", upstream: "https://[2606:50c0:8000::154]:443/C2DH/jdh-notebook/master/examples/hermeneutic-layer.ipynb", host: "journalofdigitalhistory.org", referrer: "https://journalofdigitalhistory.org/en/fingerprint-explained"

Problem to display articles:

I restart the production
Many:

110: Operation timed out Timeout when page call the api
101: Network unreachable when page linked to GitHub ( guidelines / preview notebook)

See log here

The call to /api/articles/?limit=100 is now monitored with Uptime Kuma http://dev.c2dh.uni.lux:3001/dashboard/22

But this does not mean you can leave it like that:

• Your sysadmin must monitor the server in order to find possible bottlenecks;
• Your dev team must investigate the call. It actually takes around 1s to get the response which is quite high.
