I can see a \_connections field defined in the pagesmobile table schema

> <https://github.com/HTTPArchive/bigquery/blob/master/schema/httparchive_schema.sql>

but if I try to query it the values are all zero.

```sql
SELECT COUNT (_connections)

FROM [httparchive:runs.2014_10_15_pages_mobile] where _connections != 0

```

Any ideas?

@stevesoudersorg is it a desktop only metric?

The number of connections ("\_connections") is not available from WebPagetest for iPhone.
