Cryptocurrency Exchange Kraken Suddenly Goes Dark For Two Days (sfchronicle.com) 118

Posted by EditorDavid from the releasing-the-kraken dept.
An anonymous reader quotes the San Francisco Chronicle: One of the biggest cryptocurrency exchanges was down more than 40 hours this week, causing clients to freak out... San Francisco's Kraken went offline at 9 p.m. on Wednesday for maintenance that was initially scheduled to last two hours, plus an additional two to three hours for withdrawals, according to an announcement on the company's website. "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," according to a status update on Kraken's website posted early Friday. "This means it may still take several hours before we can relaunch." Shortly after noon, the company said it was "still working to track down an elusive bug which is holding up launch." It promised customers "a substantial amount of free trading" after the problem was resolved. In previous updates, Kraken mentioned it is working on "unexpected and delicate issues" and assured clients their funds were secure, adding that "Yes, this is our new record for downtime since we launched in 2013. No, we're not proud of it."
It's 53 hours after the downtime began, and their web page is still showing the same announcement.

"Kraken is presently offline for maintenance."

  • They're at ~99.5% service availability for all of 2018 if they're at the 45 hour outage mark and come back into full service right away. That's a lot, lot worse than Citibank and the Visa network, as examples. Anyone want to place odds on that number falling to ~3.5% for the year?

    • I think you need a new calculator

      You can do the approximate math in your head. Down 45 hours is approx 2 days and we are 13 days into Jan. 20% of 13 days is 2.6 days.

        You do this wrongly. Uptime/availability is always calculated for a fixed period that is selected in advance. It is never done as downtime vs. elapsed time. That is just something amateurs do.

        And actual technical glitch that you were trying to solve before relaunch would get abandoned after some number of hours (days) without a successful fix. You don't have to leave the site down for a "technical glitch," you leave it down because the sky fell on your head and there is no reason to turn the server back on. Like, if all the money is gone and you turn the server on, people try to get their money, and can't, and want to know why.

        Exactly.

        And I repeat, the fact they cannot even put a decent splash page (which is among the first things one must implement), that is telling.

        My actual thought was "I don't care what the reason is, bitcoin is so volatile that being down over two days is ridiculous. Isn't everyone who uses them going to abandon them ASAP?".

        There are too many possible hitches, so I didn't even try to guess what they were. But it sounds as if they put up new software without running it in parallel for awhile first as a trial. (On duplicate hardware.) We used to do that for matters a lot less sensitive to our clients.

    Recently the third party that does domestic wire transfers to a bank account made a mistake communicating with Kraken's systems and they paid me around $400 twice. I told them about it and offered to reimburse them but their support staff never got back to me about how to do so and basically just locked one of my latest deposits and most of my accounts. I even offered to straight up paypal them the funds to get my account unlocked. No response. So if this happened on a larger scale to more people, they just lost A LOT of money. Btw wire transfers are expensive at most banks so just use Coinbase, they do it as a free direct deposit. Oh and also their system actually works.

    • they paid me around $400 twice. I told them about it and offered to reimburse them but their support staff never got back to me about how to do so and basically just locked one of my latest deposits and most of my accounts.

      Lesson: don't complain if you get free money. Of course, be ready to return it later if you're asked to. As the general principle goes, it's easier to ask forgiveness later than get permission up front.

      I assume you have enough cryptocurrencies locked up in the account to care. That's the topic for another lesson (don't trust exchanges for any substantial storage) though I understand issues like high withdrawal fees making small withdrawals infeasible.

    It's amateur hour stuff like this that keeps fucking up the market. Coinbase and their sketchy release of BCH trading just as Bitcoin had peaked, tanked the market a month ago. Now I fully expect this news to do the same once it becomes widespread.

    If you're going to be running a major currency exchange, why the hell are you taking down and deploying into production systems?

    With the world of VMs these days, duplicate your entire fucking production environment over to new VMs. Leave the original environment up and running to keep serving customers. Deploy into the new duplicated VM environment. If all passes sanity testing after deployment, cut the traffic over from the old production environment to the new production environment. With VMs, all they should need is a shitload of RAM and disk space. CPU usage will be low on the new environment that deployment is being done on, and once customers cut over that usage will just drop on the old VMs and pickup on the new VMs.

    If the whole thing goes tits up, you still have your old prod environment you can cut all the traffic back over to. if it all goes well, after some amount of time you can decommission the whole old VM environment.

    Aside from being able to safely deploy, having a duplicated prod environment, hopefully in a separate datacenter gives you redundancy during the time between deployments

      Good. So how do you "duplicate" the other end of a transaction to a bank for your testing? This isn't supposed to be a trick question; you have dummy accounts set up specifically for testing purposes, and/or a simulator. I wouldn't be surprised if they didn't have the first, and had an insufficient in-house written version of the second.
