We (TOG|Falcons) have had two consecutive challenges aborted by servers not coming up for our matches.

I don't normally put these things in the forums but as I cant get hold of an admin to fix it at the time, I would like to know why it is happening and if it will be fixed?

Happens.

If both teams come to terms, you can use your own.

Don't use cg servers much anymore and usually are prepared for the server to be up because majority of the time the match maker doesn't seem to work. Squad rush matches always seem to work but on shoddy servers
