Quad9 features and specs

Privacy-Focused
Quad9 does not store any personal data about users and maintains a stringent privacy policy, ensuring that your DNS queries are not tracked or sold to third parties.
Security
Quad9 provides robust security features by blocking access to known malicious domains, which helps protect users from phishing, malware, and other online threats.
Performance
With a global network of servers, Quad9 offers fast DNS resolution, which can contribute to quicker website load times and improved overall internet browsing experience.
Easy to Set Up
Changing your DNS to Quad9 is straightforward and can be easily configured on most devices without requiring technical expertise.
Free Service
Quad9 offers its DNS services free of charge, making it an accessible option for anyone looking to improve their online privacy and security without additional costs.

Possible disadvantages of Quad9

Limited Customization
Quad9 does not offer as many customization options as some competing services, which may be a drawback for advanced users looking for more control over their DNS settings.
Possible Geolocation Issues
Using a global DNS resolver like Quad9 can sometimes lead to geolocation issues, where content or services are delivered based on server location rather than user location.
Not as Established
Quad9 is a relatively new entrant in the DNS space compared to longstanding providers like Google Public DNS and OpenDNS, which might make some users hesitant.
Dependency on Upstream Filters
Quad9's security filtering relies on upstream threat intelligence providers. Therefore, the comprehensiveness of the protection is dependent on the accuracy and timeliness of these third-party sources.

Node.js features and specs

Asynchronous and Event-Driven
Node.js uses an asynchronous, non-blocking, and event-driven I/O model, making it efficient and scalable for handling multiple simultaneous connections.
JavaScript Everywhere
Developers can use JavaScript for both client-side and server-side programming, providing a unified language environment and better synergy between front-end and back-end development.
Large Community and NPM
Node.js has a vibrant community and a rich ecosystem with the Node Package Manager (NPM), which offers thousands of open-source libraries and tools that can be integrated easily into projects.
High Performance
Built on the V8 JavaScript engine from Google, Node.js translates JavaScript directly into native machine code, which increases performance and speed.
Scalability
Designed with microservices and scalability in mind, Node.js enables easy horizontal scaling across multiple servers.
JSON Support
Node.js seamlessly handles JSON, which is a common format for API responses, making it an excellent choice for building RESTful APIs and data-intensive real-time applications.

Possible disadvantages of Node.js

Callback Hell
The reliance on callbacks to manage asynchronous operations can lead to deeply nested and difficult-to-read code, commonly referred to as 'Callback Hell'.
Not Suitable for CPU-Intensive Tasks
Node.js is optimized for I/O operations and can become inefficient for CPU-intensive tasks, slowing down overall performance due to its single-threaded event loop.
Immaturity of Tools
Compared to more established technologies, some Node.js libraries and tools still lack maturity and comprehensive documentation, which can be challenging for developers.
Callback and Promise Overheads
Managing asynchronous operations using callbacks or promises can lead to additional complexity and overhead, impacting maintainability and performance if not handled correctly.
Fragmented Ecosystem
The fast-paced evolution of Node.js and its ecosystem can lead to fragmentation, with numerous versions and libraries that may not always be compatible with each other.
Security Issues
The extensive use of third-party libraries via NPM can introduce security vulnerabilities if not properly managed and updated, making applications more susceptible to attacks.

The Great DNS Trail
So assuming the answer to a query of what something like dev.to is mainly starts at the locally designated DNS servers. This will most likely be your ISP but it's not uncommon to utilize public DNS servers such as Quad9, Google, and Cloud Flare. Public DNS servers were popularized after "certain ISPs" decided that showing ad littered pages for unknown domains was a good idea. - Source: dev.to / 3 months ago

Firefox has surpassed Chrome on Speedometer
Depends on your region and what sites you're using. I live in the middle of nowhere far from civilization, and 1.1.1.1 returns terrible IPs for many sites including google.com (which pings at 350-400 ms if you resolve it through 1.1.1.1, but at 90-100 ms if you're using any other resolver). They do it because they block EDNS0 in order to protect your privacy or something like that. So I use 8.8.8.8 and 9.9.9.9 in... - Source: Hacker News / about 3 years ago
