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

Posted by EditorDavid on 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."

      With that, you need to ensure any database changes can be made independently of the code in your prod and staging environments - ensuring both forward and backwards compatibility - or anything short of a cut-over can lead to data integrity issues. If you can ensure referential data integrity, that business logic is not simultaneously executing on the prod and staging instance, and that your load balancing instances are properly configured, than yes, itâ(TM)s a great architecture and development methodology. However, it requires extensive testing - and not just happy path.

      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.

      You duplicate the database to the new prod env. Do testing against real data, then when you're satisfied dump all the data and resync it from the old prod. Once the two are in sync you can do a short maintenance period where all transactions and stopped so there's no midflight transactions during cutover.

      Or duplicate all of old prod data to new prod for testing, when satisfied dump the data. Put in a maintenance period where transactions are stopped and point new prod to old prod's database and perform the cutover. In theory with this method you might not have to put old prod into any kind of maint window. Setup your load balancers to only have new sessions only goto the new prod environment, all new sessions go there. Old sessions finish up on the old environment and dwindle down. All depends on the risk you want to take and if there were any changes to how data is stored/written to the DB in old and new prod

      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.

      Exaaaaactly. That's how you do it. Unfortunately, it is all the obvious that many of these exchanges are being run by amateur recent grads, code monkeys and keyboard cowboys that program for the happy case only.
