**Gerhard Lazu:** So I think in end of April, beginning of May we switched on the 2021 setup, and we had a show, we had an intro, we did a couple of things, episodes -- do you still remember which episode that was on Changelog, Adam? |
**Adam Stacoviak:** No, but I have the internet, and I will look it up... So give me a moment while I look it up. |
**Gerhard Lazu:** That is a good one. That was meant to be part of Ship It, but then some timelines got moved around, and that went on Changelog... And then the Ship It - we did the intro to the show. So that's how it happened. |
**Adam Stacoviak:** It was an interesting maneuver, a last-minute maneuver from us too, which - I'm not sure it matters to the listeners, but I think it was kind of... We had a plan, and then at the last minute we changed the first ten years of running down the field, so to speak. That was episode 441 on the Changelog'... |
**Gerhard Lazu:** I think that change made a lot of sense, and that change just led to a couple of other things... And now we're finally in the point to talk about the next improvement, so you don't have to wait another year; not only that, we're doing things slightly differently. We're going to share the things that w... |
So - Fastly. I would like to mention that, because Fastly, our partner - amazing CDN - had an outage a couple of weeks back. |
**Adam Stacoviak:** Unexpected, of course. |
**Jerod Santo:** Right after you said 100% uptime. |
**Gerhard Lazu:** Exactly. |
**Adam Stacoviak:** Exactly. \[laughter\] No, it was like a week after, wasn't it? That show shipped, and the very next week - Fastly outage. And it was a global outage, too. |
**Gerhard Lazu:** It was global. Half the internet broke. It was the biggest Fastly outage that I am aware of. So what that made me realize is that Fastly is great when it works. And when it doesn't, it doesn't affect just us, it affects everybody. BBC was down, and that's a big one, BBC being down. Emojis were down, o... |
**Jerod Santo:** Wait, wait, wait. Tell me more. How were emojis down for the whole internet? It doesn't make sense. |
**Gerhard Lazu:** \[08:01\] Well, apparently, the assets that were served by AWS had something to do with it. I don't know exactly in which capacity, but AWS was serving certain emoji assets, and Fastly was part of that... And emojis stopped working for Slack, so I think in the Slack setup somewhere -- I mean, everybod... |
**Jerod Santo:** That makes more sense than "The emojis just stopped working globally", across the entire world of devices... But yeah, inside Slack. |
**Gerhard Lazu:** Sensational. It's news, it has to be sensational. \[laughter\] |
**Jerod Santo:** Well, most importantly, we were down, so most importantly to us... So the BBC being down - tragic; terrible for lots of people. But for us specifically, we were down, and that was the worst part about it, wasn't it? |
**Gerhard Lazu:** For us, yes. As for all the listeners. \[laughs\] Right. And interestingly, during this time, our origin, the backend to Fastly was up. It didn't have an issue. So this month I got a report, we were down for 21 minutes because of that. So 99.96% uptime. |
**Jerod Santo:** So you had a cutover though; you turned off Fastly basically, right? |
**Gerhard Lazu:** Yes. I jumped in, switched Fastly... Basically every routed traffic; so DNS updates, and Changelog.com would start resolving directly to the Linode host, talking to the Linode load balancer, node balancer, and Fastly was basically taken out of the picture. But because of how DNS is cached, it took a c... |
I was basically chilling, it was like a day off... It was a great one. I was in the garden, just chilling. \[unintelligible 00:09:51.07\] As you do, exactly... And then the phone started going off like crazy. That was really like "What?!" I got SMS messages, because we have multiple systems... When something is down, y... |
**Jerod Santo:** Grafana, yeah. You didn't let me guess. I was gonna guess it. |
**Adam Stacoviak:** I thought you were saying you had a day off because of all the down \[unintelligible 00:10:22.20\] |
**Jerod Santo:** Grafana? Was it Grafana? |
**Gerhard Lazu:** Yes, Grafana. Sorry, Adam, what were you saying? |
**Adam Stacoviak:** I was saying I thought you said you were taking the day off because you had nothing to do because the internet was down, essentially. That's what I thought you were saying. |
**Jerod Santo:** Oh, no. |
**Adam Stacoviak:** I misunderstood. |
**Jerod Santo:** \[unintelligible 00:10:35.29\] |
**Gerhard Lazu:** I was just chilling. It was a gorgeous day, sunny, and it was a day off; I was sunbathing. I won't go into more details with that. \[laughs\] |
**Jerod Santo:** Well, let me say two things. First of all, thanks for springing into action and bringing this back up; 21 minutes, nothing wrong with that, compared to the BBC, those suckers, they were down for much longer... But the bummer side, let me tell you the bummer side, which - I haven't told you this before,... |
**Adam Stacoviak:** Yeah. |
**Gerhard Lazu:** \[11:56\] I remember that, actually. I remember that, because I remember looking at the stats, and the stats were down, and I was thinking "I wanna talk to Jerod about this." So if there's one lesson to learn from this, we need to double up. So everything that we do, we need to do two of that thing. S... |
**Jerod Santo:** Well, it's one of those ROI kind of conversations, and I think this is a good conversation for Ship It, like "What's worth doing?" and the fact is that in our five years of being on Fastly, this is the first incident they've had... And if it didn't happen to be right when we released a popular episode ... |
So the question becomes "What does it take to get that redundancy? What does that redundancy cost, and what does it gain?" And in the case of stats, I'm not sure what side of the teeter-totter we actually end up on, because the way it works now as Fastly streams the logs of all of the requests to the mp3 files over to ... |
But what would it take to get Linodes doing the same thing, or changing the way we do our stats, so that we're either redundant or do it differently? I don't know the answer to that off the top of my head. |
**Adam Stacoviak:** In the case of something like Grafana though, I would put that back on them. We shouldn't have two Grafanas. I think this is probably the case for multi-cloud - wouldn't it make sense then to be let's say on GCP, Azure, or essentially multi-cloud? And maybe that's an issue with cloud at large. The c... |
**Gerhard Lazu:** Now, obviously, as you would expect, I think about this differently. |
**Jerod Santo:** \[laughs\] Please tell us. |
**Adam Stacoviak:** Please tell. |
**Gerhard Lazu:** The way I think about this is that we are in a unique position to try out all these providers. We have the know-how, and really, our integrations are fairly simple... So I know that it wouldn't take that much more to integrate Cloudflare. So how about we use Cloudflare AND Fastly? ...the two biggest C... |
\[16:06\] Now, the pipeline that orchestrates all of that will be interesting... But this is not something that's gonna happen even like in a year. It's slowly, gradually... It's maybe a direction that we choose to go towards... And maybe we realize "You know what? Actually, in practice, Cloudflare and Fastly - it's ju... |
**Adam Stacoviak:** Yeah, that's that cost that Jerod was talking about - how much does the redundancy cost, and how much does it gain you? |
**Gerhard Lazu:** So from a CDN perspective we just basically have multiple DNS entries; you point both Fastly and Cloudflare to the same origin - or origins in this case... \[unintelligible 00:16:44.19\] The configuration is maybe slightly different, but we don't have too many rules in Fastly. How do they map to Cloud... |
**Jerod Santo:** Yes. And I looked at Cloudflare - it was probably two years ago now - with regards to serving our mp3's, and where I ran into problems was their visibility into the logs and getting that information out paled in comparison to what Fastly provides. So we would lose a lot of fidelity in those logs, like ... |
**Adam Stacoviak:** Yeah, if they've improved their logs, then it's back on the table, let's say. |
**Jerod Santo:** Yeah. So that's maybe the long-term direction. What's some stuff that is more immediate, that you have on the hitlist? Things that we should be doing with the platform. |
**Adam Stacoviak:** I think multi-CDN makes sense to me, just for those reasons. If you've got one that goes down, then you've got another resolver. |
**Jerod Santo:** But once in five years... How often is Fastly down? |
**Gerhard Lazu:** Okay, I'm thinking about this from the perspective of the experience and sharing these things. |
**Jerod Santo:** Right. |
