2nd line, with a bit of 3rd line, 70/30 id say. we have a 1st line team, then a remote team, then a user support team, then a IS team, then a fixing team. if that does not work, it comes to us to fix hehe...
if we cant do it, no one can lol, but we have a few VIP teams and server people we can chat too. So yes, 2nd line with 3rd line duties too.
All good fun, unle 1/2 the team are on holiday + sick, then it gets busy!
