According to Bioware producer Fernando Melo (via Twitter), Mass Effect: Andromeda uses so called peer to peer (P2P) for its multiplayer mode. This means there are no dedicated servers for people who play Mass Effect online.
This has caused a lot of discussion on Reddit and as expected, some didn't see it as a problem, while others declared the multiplayer of Mass Effect: Andromeda will be unplayable weeks after release.
We need to wait and see how it turns out. Luckily the wait is almost over. Mass Effect: Andromeda is releasing on March 23rd on PC, PS4 and Xbox One. And we'll get to sample the co-op at PAX East next week.
