🐛cloudflared connects all 4 connections to the same data center

[perosb]

Describe the bug
For high availability, cloudflared should (accroding to the documentation) connect 4 diffrent conenctions to 2 different data centers.

We've had 2 different tunnels in two different AKS clusters get disconnected at the same time (that's 8 connections).
This seem to at least happen in FRA.

Another tunnel in SE connects to ARN and TLL just fine.

Ref documentation https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/deploy-tunnels/deploy-cloudflared-replicas/

To Reproduce
Steps to reproduce the behavior:

1. connect a cloudflared tunnel from AKS Germany West Central
2. Observe which data centers connecting to

If it's an issue with Cloudflare Tunnel:
4. Tunnel ID :
5. cloudflared config:

Expected behavior
It should connect to f.ex. FRA and TXL

Environment and versions

• OS: k8s 1.30
• Architecture: AMD
• Version: 2024.11 (happens on lower too)

Hi @perosb, this is expected behavior. We have some large locations such as FRA that are split into multiple data centers. In your example, you are connected to 4 different data centers, fra06, fra08, fra10 and fra17.
