I just now lost 2 bids on 2 centers over 40k salaries, because the site happened to crash for about 3 minutes. I would say that this happens too often for the auction timer to be just 3 minutes.
I mean to lose on 2 bids because the site went down for 3 minutes is just frustrating and annoying. It may be far fetched but it does slightly raise suspicion on how the site can be down for 3 min exactly on the time i got overbid. Especially when the site runs well right before and right after the downtime. That's what it makes me frustrated.
Anyways, I say put back the 5 minute timer, because 3 minutes goes by far too fast. Especially when downtimes may occur.
