This is just a guestimate, but it's way better than anything the geniuses behind 'the best bitcoin exchange' have been able to say:
Kraken will successfully upgrade it's systems on the day Hell freezes over, pigs fly and we witness the return of Elvis.

In my kitchen hell there is a freezer, I managed to get pork into a temporary state of airborness and btw Elvis is not dead.
But the first one regarding Kraken seems to be moving more slowly.
Probably in trouble for even paying a development team since customer fund withdrawals are painfull, too.
System upgradeWe will be performing a system upgrade on Thursday, January 11 at approximately 5:00 UTC (Wednesday January 10 at 9 pm PT).That should have been 7 hours ago. Any metrics so far about failed orders? Where can I even see the version number of the current engine?
Somebody has been publishing those metrics occasionally, orders placed/failed ratio, I do lack the technology to do relyable measurements.
