Atlassian Exceeds 99.9999% of Availability Using Sidecars, Fault-Tolerant Design
- warent 4y agolol. They just had a multiple week outage this year. No, they cannot claim this level of availability until around May 2023. This is marketing nonsense trying to cover their massive April mistake.
- h2odragon 4y ago"fault tolerant design" == "we knew the design was faulty, we tolerate that"
- miscaccount 4y agoWell technically their system was up and running . Except that they did not have data to work on. /s
- rozenmd 4y agoThis part of the system didn't go down. They just deleted a shit ton of customer data, and had to manually restore it. The system itself was still available if your data wasn't part of the deletion script.
- hericium 4y agoDidn't Atlassian irreversibly lost Confluence data of some of their clients this year after weeks-long outage?
- dang 4y agoUrl changed from https://www.infoq.com/news/2022/09/atlassian-high-availability/ https://www.infoq.com/news/2022/09/atlassian-high-availabili..., which points to this.
- itsdrewmiller 4y agoCan you change the title too to something that doesn't seem like they are trying to mislead people? The real title is "Here’s how one of Atlassian’s critical services consistently gets above 99.9999% of availability"
- dang 4y agoIf someone can suggest an accurate, neutral title, preferably using representative language from the article itself, we'll happily change it. (I'd do it myself but am just being pulled away)
- kayodelycaon 4y agoExactly which part of their system has 6 9s? It certainly hasn’t been Jira.
- MiscIdeaMaker99 4y agoIt's mentioned in the article.
- posnet 4y agoThe title is very misleading, it is just one of their micro-services that has that uptime.
- MiscIdeaMaker99 4y agoYes, exactly. It's their Tenant Context Service. The headline is misleading, but really only for those who don't bother to read the article.
- grnmamba 4y agoHeadline: "Smoking does not cause cancer." Article: "This study proves that smoking does not cause skin cancer."
- sebslomski 4y agoInteresting. * Atlassian: We estimate the rebuilding effort to last for up to 2 more weeks: https://news.ycombinator.com/item?id=30990697 https://news.ycombinator.com/item?id=30990697 * Inside the longest Atlassian outage: https://news.ycombinator.com/item?id=31015813 https://news.ycombinator.com/item?id=31015813 * Atlassian products have been down for 4 days https://news.ycombinator.com/item?id=30973808 https://news.ycombinator.com/item?id=30973808 * Post-incident review on the Atlassian April 2022 outage https://news.ycombinator.com/item?id=31210469 https://news.ycombinator.com/item?id=31210469
- jsiepkes 4y agoYes, but you see, that wasn't a full outage because not all customers were affected. So therefor it doesn't count as downtime according to the SLA... :')
- oxfordmale 4y agoJust checking the Atlassian status page and there is an active incident:-)
- atulvi 4y agoIs JIRA not included in this calculation? They were down many times last year.
- grnmamba 4y agoThis is the worst attempt at corporate propaganda I've seen in a while. https://www.atlassian.com/engineering/post-incident-review-april-2022-outage https://www.atlassian.com/engineering/post-incident-review-a...
- CyanLite2 4y agoMisleading Title. Should be: "Besides that Mrs. Lincoln, how was the play?"
- xorcist 4y agoAn availability of 99.9999% means a maximum of 31 seconds unavailable per year. The usual "five nines" is 5 minutes, and that's a tough target for anyone. Given that their outage was from April 4 to April 19 this year, they should reach their target availability on average at the earliest in the year 45222. If they keep perfect uptime in the meantime, that is.
- 0xbadcafebee 4y agoAtlassian's status pages have had "active incidents" for the last two days straight: https://status.atlassian.com/ https://status.atlassian.com/ Six nines of availability means no more than 30 seconds downtime per year. Maybe the fault tolerance of one system isn't such a big deal if you depend on 30 other systems?
- mkl95 4y ago> Atlassian Engineering recently published how it exceeded 99.9999% of availability with its Tenant Context Service (TCS). What a misleading and cynical headline. Literally all Atlassian products I work with have some unexpected downtime every now and then.
- jayanmn 4y ago>achieved this high availability by implementing highly-autonomous client sidecars, able to proactively shield themselves from complete AWS region failures. complete region fail? How often does that happen?
- timcavel 4y ago
- fipar 4y agoI think this is relevant regarding the very misleading availability percentage in the title: https://rachelbythebay.com/w/2019/07/15/giant/ https://rachelbythebay.com/w/2019/07/15/giant/
- rwbhn 4y agoActual title: Here’s how one of Atlassian’s critical services consistently gets above 99.9999% of availability
