Ugh I hate answering interview questions. Even more so when they are being asked as part of an application.

Collateral Damage posted:On the topic of database performance a pitfall I've run into a few times is that your database engine will cache tables in memory and as long as your tables are small enough to stay cached you won't notice how inefficient your queries are because it's still lightning fast as long as they're in RAM. So you load up a few gigs of test data and run your tests and everything passes with flying colors, so you sign off and put it in production. Database and query optimizations are something that scratches the itch for me. I don't know why, and I'm not very good at it, but I love tucking into a performance problem like that. It's not unheard of to see hundreds, even thousands, of times performance increase if you know what knobs to turn.

'd pretty hard at the idiot on Twitter telling them to just bring the game to Xbox and get more servers for free. Bing bang boom, so simple it is never simple. So my boss has had me shadowing our netops team since I got my CCNA at the end of last year. They've been great and it's nice just seeing most of the stuff they're doing isn't stupidly overwhelming to me at this point. Though most of them are short timers as they were laid off after our merger went through, and will be leaving the company at some point next month. They're all pretty sanguine about it since they knew well ahead of time and seem to be getting solid severance packages. My division was untouched for whatever reason, but some of these guys seem to think I'm going to be taking over their roles once they leave (network engineer), which lol no, I am still only a desktop support tech. I did have a conversation with my boss about how they did have some patching they had to do late on a Saturday, and I didn't attend/observe because I'm hourly and it's not my job to do so at this point. He agreed, and said that that's certainly not expected of me. I then said half joking/half serious "Yeah I'm not against doing that kind of stuff, but that requires a new job title and pay bump so lol". He laughed and then we moved into other topics. Anyways, he knows I want to pivot into the networking side of things, and has been incredibly supportive of that desire. My only hope is that either that promotion/pay bump happens sooner than later. He hasn't made any concrete promises or anything, but I'm hopeful for the future.

I get your point and who really cares in this context, but why would they set this up with a single point of failure? Final Fantasy was a pretty huge game, was 2011 a dark time before putting failover capacity in different geographic locations to manage pretty much exactly this risk was a thing you did before a production release?

Anytime I run a meeting I send a recap of what we discussed and decided. This is partly for CYA purposes, so no one can say we didn't talk about x or whatever, but it also helps me keep track of what was discussed, helps anyone who couldn't attend, and gives people something written to refer to so they don't have to rely on their memories. This all seems very basic to me, but most people are extremely disorganized and do absolutely nothing to counteract that disorganization, and I think it really helps the people I work with. I really believe that my greatest contributions are organization, not technical.

They haven't said specifically what the issue is, but it's clearly database issues. They added a max player cap as well as a max logins per minute cap. They recently said they're hosted in Azure. I'm sure they're hitting hard limits in multiple places.

They just learned from blizzard launches that if the supply of servers is low then player demand will go up. I learned something similar in econ too

jaegerx posted:You've heard of once in a century storms right? Right, natural disasters are one of the key reasons you develop and test disaster recovery plans. I think we're talking past each other, I'm not upset or anything they shut down the servers, just surprised that a large company releasing a major product didn't plan for that. If a major earthquake hits San Francisco it would be the last thing that matters, but YouTube and Netflix will probably keep on chugging.

Acquisitions always end in being stripped for parts as the company needs to inflate its balance books to compensate for the debt in acquiring the company There's a small bit of hope. Being acquired by a bigger company in industry sure, it's junkyard time. Being acquired by a PE firm that wants to pivot, grow, and sell can be alright.

Basically what they've said/implied so far is that the bottleneck is in the syncing of all global data. The game is always-online and every mission played contributes to a shared, global war effort to 'liberate' planets bit by bit. From what I can glean from the dev's occasional posts, their databases just cannot keep up with close to a million people simultaneously trying to access them. I'm not a database guy by any means so I could be pretty off base but that's really what it seems like. At one point last week they announced they were turning off a bunch of global stat tracking just to claw back some overhead
