So many system design lessons you can take from GitHub’s latest outage.
Here’s what happened:
A traffic spike caused an Istio sidecar to hit its concurrency limit.
The autoscaling policy was watching the host service, but not the sidecar’s actual capacity.
So the system didn’t scale when it should have.
One failure cascaded into another.
Eventually, four HAProxy nodes exhausted their network flow limits and the gateway authentication path started failing.
And then came the worst nightmare of an distributed system architect:
Retries.
Instead of reducing load when the system was unhealthy, retry logic generated even more traffic.
Copilot Token Service traffic went from roughly 10K RPS to 100K RPS.
This is what a real distributed-system failure looks like. The reason they grill you on edge cases in interviews.
But GitHub is currently operating at an extreme scale it was never designed for bcz of AI. It’s worth giving them some grace here.
Telugu Cinema is one big scam ….from the money that goes in, to the collections that come out….I’ll always support reviewers as long as it’s criticism,not hate.
A 400 crore budget?#Peddi shouldn’t get a technical criticism ? no broo i need more videos of such
niku oscar sinners nachadhu antav gani aadu review veyyakodadha ra @AdiviSesh
Audience should never take film makers side in this context …Bring more hate to film makers guys 👍
Got to know that Barbell's review of #Peddi on YouTube was taken down due to a copyright strike by the makers.
It's very unfair. I caught his review when he released it and he was bang on with his points.
Our filmmakers should grow up and be able to accept honest criticism.
point entante vaadu entha neechanga nitpick chesina kuda it shouldn't matter to you or the producers. afterall vaadidho youtube channel and meedhi 100s of crores worth movie product. if a single youtube video can influence people, imagine how fragile your movie product is.
Writers & actors built careers on propaganda, and the industry stayed quiet like cats. Now the same clan mock Dhurandhar. You don’t get to call yourself liberal if your first instinct is to Mock.
Don’t know when truth started getting labeled as propaganda...... strange times.
COMING TO THE POINT.....
I want to tell @AdityaDharFilms & @RanveerOfficial yeh kaala drishti aise nahi jaayega... Muthi bhar ke laal mirch se kaam nahi chalega.... poora khet jalana padega 🔥
Watched #Dhurandhar2TheRevenge last night.... Outstanding film 🙏
