MT4 demo and its servers

For those who have been using MT demo for a long time, please give some comparisions between each default server of different brokers that MT demo connected to. Now it connects to MIG with Dow Jones Newswires.

Anybody remember which broker it connected to before MIG?

Would be good if you give a comment on different news services that connected to MT. What about the speed of each newswire?

Trying MIG Demo but cannot see the news button in it.
It's gone?

OK, It comes now after opening the MT4 for almost an hour.
