Service status postings have been made, to ensure customers were aware that this was going to be rolled, and im pretty sure we've been talking about this for ages on the forums that we were going to be changing the spam tab on the portal.
Its not the fact that too many people can do major changes, its the fact that in the agile development we do we need to get things done fast as you the customer was requesting these improvements. Would you rather of waited months on end whilst we tested every single thing possible? Or have a few spam emails delivered to your inbox on one day of roll and we fix it as soon as possible... even if most of us have only had a few hours sleep
Now i undestand in some industries mistakes cant be made, i wouldn't like surgeon cutting without being tested he can do the job for example

But we're talking about emails here, its not a life or death situation.
But as i said previously, your issue has now been resolved, and if its not then shout up, i'll be more than willing to get it sorted for you. Thats what were here for.
