Roblox - a gaming company - was down for 3 days which is an infinite timespan. Roblox relies heavily on HashiCorp products like Vault and Consul, and the incident was connected to the usage of those - especially the usage of a new feature in Consul that triggered a pathological issue in its open-source engine - BoltDB. Find a summary on protocol.com, as well as a detailed Post Mortem from Roblox themselves.

Load Balancing Algorithms 👷♂️
Large-scale applications and websites often receive a high volume of traffic that cannot be handled by a single server. Load balancing distributes traffic across multiple servers, enabling efficient resource utilization, reducing downtime, and improving application performance. This article discusses various load balancing techniques, such as round-robin, weighted round-robin, and least connections. The author also provides an overview of advanced techniques such as SSL offloading and content-based routing.
Anti-Corruption Layer Pattern
If you read anything about DDD, you might have heard about the Anti-Corruption layer: a pattern useful when you have two subdomains which don't share the same semantics. Basically, you introduce a layer which will translates the messages from one system into the messages readable by the another. Find a detailed description of the pattern it's drawbacks in the article by Microsoft.
Speaking about the DDD - this Wednesday I will be holding an interview the the author of "Learning DDD" - Vlad Khononov! Press the "remind me" button in order not to miss!
And of course, this week I published an interview with Magda Miu about "What should EM know about architecture". Find it here!
