@krakensupport seems still active, so while their platform may have gone down, they haven't really gone "dark" - https://mobile.twitter.com/krakensupport/with_replies

Their platform is back online now too: https://blog.kraken.com/post/1449/

What kind of "upgrade" could be taking 48 hours and counting? Don't they have rollback capability to go back to previous working version?

The only thing I can think of would be some big database migration that went awry and they don't have strategy to roll back.

But normally you would get a dump of production database and test your migration scripts on test/staging servers against latest snapshot of prod data.

You don't just run migration script on your production database and see what happens. You try running it against last backup / snapshot of prod data first.

What else could it be?

They claim there is a bug in production that was not present on testing servers, and they are having trouble tracking it down.

Yea, database migration is my first guess as well. Any code change would have been reverted quickly otherwise. Their blog post about the incident is not clear enough. https://blog.kraken.com/post/1449/kraken-returns-with-free-t...

Either way, it looks bad from both engineering and product perspective.

A lawyer! So scary!

Probably a security hole

such drama from bloomberg. traditional media is not up to date with crypto. that was a planned update that took longer and now trading is free for the rest of the month

Got an email 8 minutes ago that they are back online.
