# Official sources

Use this reference only when you need source grounding for Huawei Cloud OBS, CBR, SFS, or EVS service behavior or the detailed source list.

## Huawei Cloud documentation

Use these as starting points, not as proof of the user's live Huawei Cloud state:

- https://support.huaweicloud.com/intl/en-us/obs/index.html
- https://support.huaweicloud.com/intl/en-us/cbr/index.html
- https://support.huaweicloud.com/intl/en-us/sfs/index.html
- https://support.huaweicloud.com/intl/en-us/evs/index.html

## Grounding rule

If live Huawei Cloud tooling is unavailable, say: "I can't query live state here, so I'm falling back to official Huawei Cloud docs." Then fall back to these sources and sanitized user evidence.
