"We are sending out new servers to our providers called "R5". They will be testing them out and changing over the servers by tomorrow evening. This server contains some fixes for the "Connection to the server has been lost" message that a lot of you will have seen.

We are also working on making another new server over the weekend as EA has set up some dedicated front-end boxes just for Battlefield Bad Company 2 which we will update the server to use and should work to improve the stability of connections to EA for everyone.  "

Another source states the servers will be up at approximately 3 AM EST.

Awesome.  When I was unable to log in a moment ago, I was hoping it was because they were doing some maintenance.  Hopefully they'll get this fixed up :D

Made me play some more SP.  The banter between bad company is quite awesome.

" @TravisT: what time is it now for you guys? how many hours from now can we expect to connect? "

Hmm, just got the 'connection lost' message and stats wipe about an hour ago. Maybe they're still working on this... (Crosses fingers)

Guess they're working on this now because the servers are down. On my day off from work. Fucking awesome.

Hate to not be playing it, but if it's gonna be for the good of the game, I endorse it.

You can still log in and play right now?
 
Server browser is just bugged and friends list isn't working at all.

On the 360 there is a ticker at the bottom of the screen saying there are server issues and I cant find any games at all. Been like this for hours.

I am finally seeing the good side of not getting this game in the post 'til Monday.

360 servers back online for me. Stats/ unlocks etc all back. Hope it stays online.

well i read on a gamespot or ign that turn off your console and wait for 20mins and turn it back it on. i tried that and it work.

I'm so happy they decided to fix the  "Connection to the server has been lost" , I lost a lot of XP the times I got the error. :/

Its been 24 hours and this shit is still happening. Haven't been able to play but maybe an hour all weekend. C'mon already.

I'm not having any issues, but there have been days where my friend has been unable to connect for hours. Weird.

Still can't connect to the servers, almost considering going back to MAG. Please, EA, save me.
