Have a meeting today with our AWS account team about how we’re no longer going to be “All in on AWS” as we diversify workloads away. Was mostly about the pace of innovation on core services slowing and AWS being too far behind on AI services so we’re buying those from elsewhere. The AWS team keeps touting the rock solid reliability of AWS as a reason why we shouldn’t diversify our cloud. Should be a fun meeting!
> The AWS team keeps touting the rock solid reliability of AWS as a reason why we shouldn’t diversify our cloud. Should be a fun meeting! This is and was never true. I've done setups in the past where monitoring happened "multi cloud" with also multiple dedicated servers. Was pretty broad so you could actually see where things broke. Was quite some time ago so I don't have the data, but AWS never came out on top. It…
AWS multiple services outage in us-east-1

#952It's not difficult, it's just that we engineers chose convenience and delegated uptime to someone else.

Re: AWS multiple services outage in us-east-1
#953Seems like major issues are still ongoing. If anything it seems worse than it did ~4 hours ago. For reference I'm a data engineer and it's Redshift and Airflow (AWS managed) that is FUBAR for me.
It has been quite a while, wondering how many 9s are dropped. 365 day * 24 * 0.0001 is roughly 8 hours, so it already lost the 99.99% status.
Re: AWS multiple services outage in us-east-1
#954Interesting day. I've been on an incident bridge since 3AM. Our systems have mostly recovered now with a few back office stragglers fighting for compute. The biggest miss on our side is that, although we designed a multi-region capable application, we could not run the failover process because our security org migrated us to Identity Center and only put it in us-east-1, hard locking the entire company out of the AWS…

#955This is having a direct impact on my wellbeing. I was at Whole Foods in Hudson Yards NYC and I couldn’t get the prime discount on my chocolate bar because the system isn’t working. Decided not to get the chocolate bar. Now my chocolate levels are way too low.
Re: AWS multiple services outage in us-east-1
#956“Based on our investigation, the issue appears to be related to DNS resolution of the DynamoDB API endpoint in US-EAST-1. We are working on multiple parallel paths to accelerate recovery.” It’s always DNS.
I don't think that's necessarily true. The outage updates later identified failing network load balancers as the cause--I think DNS was just a symptom of the root cause I suppose it's possible DNS broke health checks but it seems more likely to be the other way around imo
One particular “dns” issue that caused an outage was actually a bug in software that monitors healthchecks.
It would actively monitor all servers for a particular service (by updating itself based on what was deployed) and update dns based on those checks.
So when the health check monitors failed, servers would get removed from dns within a few milliseconds.
Bug gets deployed to health check service. All of a sudden users can’t resolve dns names because everything is marked as unhealthy and removed from dns.
So not really a “dns” issue, but it looks like one to users

I remember a meme years ago about Nestle. It was something like: GO ON, BOYCOT US - I BET YOU CAN’T - WE MAKE EVERYTHING.
Same meme would work for Aws today.

The problem is now that, what’s anyone going to do? Leave? I remember a meme years ago about Nestle. It was something like: GO ON, BOYCOT US - I BET YOU CAN’T - WE MAKE EVERYTHING. Same meme would work for Aws today.
Not really, there are enough alternatives.
