Pull request overview
This PR updates a Grafana alert rule configuration to handle null/NaN values more gracefully by changing the reducer mode from "strict" to "dropNN". The change affects how the alert processes missing or invalid metric values when evaluating internet download speed thresholds.
Key changes:
- Modified the reduce expression mode from "strict" to "dropNN" to drop null/NaN values instead of failing strictly
- Added an inline comment explaining the mode change and mentioning an alternative

The comment mentions "replaceNN" as an alternative, but the correct Grafana reduce mode is "replaceNon" (not "replaceNN"). The mode "replaceNon" replaces non-numeric values with a specified value.
Suggested change
| mode = "dropNN" # drop null/NaN values; alternative: replaceNN | |
| mode = "dropNN" # drop null/NaN values; alternative: replaceNon |
