We've had word from UBB that the upgrade of the mbs will take place on Friday. The mbs will be closed for the duration of the upgrade. I seem to recall they expected it get it done over 6-8 hours. I'm checking on that and will update this post if necessary.
So early bidding is probably a good idea.
It's a nuisance, but hopefully it'll be well worth it. We're a few upgrades behind by this point!
