Whilst I love CB, it does seem to be so fucking unstable, even at the best of times.
We did try to get an answer out of CB as to why this was, and they made an excuse that connectivity is massively diminished if you're accessing from outside of the US. If you're outside of the US, CB recommend accessing via a VPN, although this only made things marginally better for us (we used a Californian server on TotalVPN).
So, idk. You'd think they'd sort out their problems more quickly given the amounts of money at stake.
