'Http/1.1 Service Unavailable' when you click on history graph

I was logged out, logged back in and it seems ok now

I got this message too when I tried to log in via Betfair Exchange 5 minutes ago.

Only way I could get in was by going through Betfair Forum.

It seems they have corrected it for some and at the same time messed up others.

That takes some doing.

i had to go through sportsbook to get to the exchange.i have been away for a couple of weeks and things seem no better
