They don't dio maintenance on the server but i the data center, replacing switches, firewalls whatever central thing to permanently fix yesterday's issue (I assume). The probably do not have to work on the 3 servers individually.
Well, we started renting IT services outside of our company about 12 years ago - never, ever have we had an outage in a server center because they were changing switches, firewalls, routers and whatnot, Our lowest availability we offer to our customers is 99.5% and we simply couldn't fulfill this if simple maintenance jobs like those you mentioned would take the infrastructure down.
You either plan for continuous service and build your software accordingly or you have no clue what that is and start coding away. ZOS obviously has no clue.
Many people claim that maintenance in MMOs is a regular thing - I'd like to point out that Guild Wars 2, for example, even managed to roll their first expansion pack into production with 0 downtime. You get a message that a new build is available, you log off and back on - you download the new content as fast as your connection allows and - you're back into the game.
So the downtime there is individual (since you can decide when to log out to load the new build) and - except for a few cases when they patched a critical exploit - the windows in which you could remain online was between 45 minutes and 2 hours.
I've never experienced something like ESO offers with 4+ hours in which the service just isn't available. Poor software design, poor technical infrastructure. Having a dedicated server that needed downtime when you replaced components is a concept that was modern 10 years ago. Nowadays you have virtual servers and if you need more servers you just start more instances and you stop them when you no longer need them.
Of course, the datacenter hosts running those virtual servers can run into problems - all of our external providers have spare servers, though, and the longest downtime we had for single server (or instance) applications was less than an hour when the image was moved to a new ESX host. If you have an architecture that is using multiple servers already you may get a load peak and somewhat sluggish response until the new instance is online but you do not have a complete outage.

" ESO , a masterpiece in the worst hands"! I have said that already couple of times but...its true!
And fanboys take your tinfoil hats off, there is no conspiracy here. You don't do any good by trying to excuse zeni's worst behavior and incompetence towards customers and this great game.
I'm so very sorry cause i really love this game.

We're all just speculating of course (because of a no-info-policy by Zenimax, apparently), but how long do you think a data centre with this kind of problems would exist? I highly doubt that, especially since usually not all infrastructure is affected simultaneously (i.E. console servers != pc servers, etc., people staying logged in but login not working, etc.).

For one they have three servers, or four plus the accounting store they have to do. So I suspect doing each one would take time. So yeah don't expect to be in game this morning.

Another "valid" reason, of course, is when - for some reason - you cannot use virtual servers and have to change physical components but, as I said previously, (a) with some effort you can go virtual and become mainly independant of mainboard upgrades, etc. and (b) if you plan (!) on continuous service you have more than one server so even in a non-virtual environment you don't suffer from service outage if you take one server down.

Also by observing this topic further, I think maybe this time ZOS won't get away with it as easily, seems like people are finally getting fed up with it.
That's ordinary planned PS4 maintenance. But am I going crazy, or are they taking down the account system for the second time this week?Chickenstein wrote: »Oh look, the NA data centre is also being maintained!
Yeah, definitely data centre issues.
Oh, i've just read the announcement.
EIGHT HOURS AND MAYBE MORE? REALLY?! HOW IN THE WORLD IS THIS JUSTIFIED?
And i was thinking of eso+ next week. No thanks. Just buying the mmo with worst service EVER (trust someone who's been playing mmo since the MUD era) was more then enough for me, i'll wait until i finish the vanilla content first. Which, considering the uptime percentage here, isn't going to happen anytime soon. At least maybe bethesda will buy the game back from zenimax by then.

So Zenimax can only stand by and watch helplessly as the company that owns said datacentre decides to take it offline to do essential work on various areas of the centre. They haven't even told Zenimax what the maintenance actually is, but its likely connected to power problems or possibly re-organising the centre due to an expansion.
This is the 3rd or 4th Datacentre maintenance in the last 6 weeks, so something is definitely going on there.
I wonder how many of the total EU populace are at home playing during a week day and how many are out at work/college/school etc. From my limited experience the hubs are rammed in the eveings but dead in the day times.
Maintenance while im at work, all ready for me to jump into on an evening suits me very (selfishly) well
But, look at all the new stuff in the Crown Store...
But Bethesda should really act up imo,
ZoS is giving the much beloved Elder Scrolls series a bad name.
Am sure that there are companies that would take much better care of the game and the customers.
