Kraken.com down since 1 day( Edit BACK ONLINE) - System upgrade

Hello steemians.

So if you visit kraken.com you will see a friendly string which looks like this.

If you follow this page: https://status.kraken.com/

You see that they have some "little" problems to get their server back and running. They claim that they have more issues to do the updates. Me as a softwaredeveloper by myself ask: Dont they even test their systems in a development environment ?

I will paste all their text here just to keep the info:

Update - We are still working to resolve the issues that we have identified and our team is working around the clock to >ensure a smooth upgrade.

This means it may still take several hours before we can relaunch the site.
Jan 12, 12:05 UTC
Update - We are still working on the upgrade and may be offline for several more hours. Will provide another update >when we get closer to coming back online.

This means the Site will not be up after 9:00AM UTC (1:00AM PT).
Jan 12, 08:00 UTC
Update - We are close but rather than launch immediately ahead of the team passing out, we will push off a bit to get >some rest and be able to better monitor systems and react to problems following launch. Unfortunately, this means >several more hours of delay. We do not have a definite time but it will not be before 9:00AM UTC (1:00AM PT).
Jan 12, 03:46 UTC
Update - Thank you for your continued patience while we work through these unexpected and delicate issues. We are >continuing to make progress but don't have a specific timeline for relaunch at the moment.
Jan 12, 03:11 UTC
Update - Inching our way to the finish line over here, devs mainlining coffee. Funds are all secure and protracted >downtime has nothing to do with funding/reserves. Yes, this is our new record for downtime since we launched in >2013. No, we're not proud of it. Working hard to ensure that when we come back online things are running as smoothly >and safely as possible. We'll give you another update in a few hours or as soon as we have something new to report.
Jan 12, 00:43 UTC
Update - We are making progress on the few remaining issues but don't have a definite launch time yet. We intend to >cancel stale (and possibly all) orders and pause liquidations upon resuming service. More details to follow soon. Thank >you for your patience.
Jan 11, 21:41 UTC
Update - We are currently working to resolve a number of issues that came up during final testing. At this stage it is >uncertain when exactly these issues can be fixed, but we will update again when a more definite ETA can be given.
Jan 11, 19:07 UTC
Update - In the final stage of installing the upgrade now. We are getting close but hard to give an exact ETA since it >depends on how the final testing goes.
Jan 11, 15:27 UTC
Update - The upgrade is going much more slowly than anticipated. It will probably be two hours or more until systems >are back online.
Jan 11, 12:14 UTC
Update - We are still working on the upgrade and may be offline for another hour or more. Will provide another update >when we get closer to coming back online.
Jan 11, 10:01 UTC
Update - We got a late start and the upgrade is moving slower than anticipated. We now expect to be able to bring >services back online by Thursday, 10:00am UTC (2:00am PT) but will keep you updated as we get further in to the >process.
Jan 11, 07:34 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Jan 11, 05:00 UTC
Scheduled - We are performing a system upgrade on Thursday, January 11 at approximately 5:00 UTC (Wednesday >January 10 at 9 pm PT). Kraken services will be offline for about 2 hours during the upgrade, possibly longer. >Withdrawals in all currencies will be offline for an additional 2-3 hours after other systems come online. If you submit a >withdrawal request while withdrawals are offline, the withdrawal will be sent after withdrawals come online again.

I hope for all people who still have some money /currencies on that exchange that they will be back soon.

I let it up to you if you get worried or not...

Edit:

If you look to their Eth adress there was a transaction of 180 Eth but seems just internaly. But no Eth was send out.
