# Location colour change

## Overview

This page explores reasons for location colours.

## Any/All behaviour for locations

*Location tile set to "React to ALL issues" with subwatches*

In this example, the two bearers in this location are down, displayed in red. The VLANs are no longer receiving data and are stuck in an artificially green state. Highlight will ignore the state of the sub-watches and show the whole site as red and down. The bearers are "major" watches which can override the state of "minor" watches if all are red in a location. A list of major and minor watches is shown in the table below.

The same logic applies to locations in the Grid.

| Major                      | Minor             |
| -------------------------- | ----------------- |
| SDSL (bearers)             | Cellular          |
| ADSL (including Broadband) | Switches          |
| Dedicated access bearers   | Performance tests |
| Tunnels                    | Classes           |
| WAPs                       | VLANs             |
| Controller Status          | MLEs              |
|                            | Cameras           |
|                            | Sensors           |

#### Exception in the App Tests column

If the watches in an App Test cell are a mix of greens and non-greens, then the resultant cell colour is amber.

#### Additional explanation

For any location or grid cell, take the worst colour of all watches in that location or cell, and if 'ALL' selected, restrict location or cell colour to amber only if there are any 'Major' watches that are green in that location or cell. The "worst of all watches" includes subwatches like performance tests and "restrict to amber" only works if there are extra watches of the 'Major' type that are green - not any other colour.

With ALL selected, the location or cell can only be red if all 'Major' watches in that location or cell are red.

## Status: red location - other causes

If a location and strip chart are amber or red with a stability issue, but information is still being accumulated once on the Details page, it is possible the watch is unreachable from one of the Highlight Pollers. [Contact us](https://help.highlight.net/getting-started/contact-us) to check if this is the case.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.highlight.net/troubleshooting/location-colour-change.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
