When I first began interviewing with Cloudflare in the Spring of 2019, I came across a Cloudflare blog post announcing Proudflare, the company’s LGBTQIA+ Employee Resource Group (ERG). The post gave me a clear sense of the company’s commitment to diversity and inclusion. I could tell this was a place that values and celebrates diversity, which really appealed to me as I progressed through the interview process with Cloudflare, and ultimately accepted the role.
Fast forward to my Cloudflare new hire orientation, two weeks of training and introductions at our San Francisco HQ. We learned about the various ERGs at Cloudflare including one for Latinx employees. While I had a strong desire to be part of a Latinx ERG, it was clear that the group was actually in need of someone to lead the effort and rally the troops. At Cloudflare, we have offices across the country and around the world. I wasn’t really sure how to launch an ERG that would be global in scope. After meeting with leads from other Cloudflare ERGs, understanding the landscape, and attending an external workshop, everything started to come together.
In early August, we officially gave ourselves Continue reading
Broadband in space: The Associated Press, via the New York Post, has a story on the new space race involving Amazon, SpaceX, and other companies. The competition is to be first to deploy new satellite networks to provide broadband service to all corners of the Earth. Still, there are some questions about these low-Earth orbit satellites, with the multi-billion-dollar cost of deployment being the biggest concern.
Secure by algorithm: Researchers at Princeton University have developed algorithms that they say can prevent hacker attacks on power grids, DownToEarth reports. The new algorithms target power spikes that could be driven by IoT-based attacks. One algorithm would prevent connections overloading by balancing power, and the other would help grids restore their functionality after an attack.
Please help: A column at ZDNet asks network operators to using existing tools to fix security problems with the Border Gateway Protocol, which routers use to tell each other the best way to route traffic. The BGP standard includes Route Origin Authorizations (ROAs) to confirm the accuracy of routing messages, but those tools aren’t as widely deployed as they could be, the column suggests.

There are so many good resources for Network Engineers out there. I started to share the ones I liked on beginning of this month. Click here to see previous Networking Recommended Resources. As you know, I share 5 resource every week. There are so many in my list already, I can’t wait for the next …

I have exciting news I’d love to share with you: we’re launching a new online course focused on networking in public clouds starting in February 2020 (I’ve been mulling over this idea and polishing the concept for almost 18 months, and finally it all came together ;)
With Go To The Cloud becoming the answer to all questions (regardless of what the question is), you can find tons of materials describing various aspects of public clouds, so you might wonder why I decided to enter the fray. The answer is simple: with everyone being focused on developers, there’s not much that an infrastructure engineer could use to help him survive when the developers move on and he’s left to manage whatever they put in place.

Every few weeks I stumble upon an article (or twitter storm) in which someone claims you don’t need formal education to get started as a Software Engineer (or whatever else) - all you need is a coding academy/bootcamp and you're all set.
George V. Neville-Neil wrote a hilarious rebuttal of this idea followed by some pretty good advice. Hope you’ll enjoy it as much as I did ;)
I want to show you how to configure a host server so, when it is shut down, it executes a script that runs commands on any running virtual machines before the host tries to stop them. I will configure the host server to wait until the script completes configuring the virtual machines before continuing with the shutdown process, shutting down the virtual machines, and eventually powering off.
I had to learn how Systemd service unit configuration files work and some more details about how Libvirt is configured in different Linux distributions. Read on to see the solution, plus some details about how to test the solution in Ubuntu and CentOS.
Create a new Systemd service named graceful-shutdown that runs a script when the host system shuts down, but before Libvirt shuts down any virtual machines. Ensure that the libvirt-guests service is already started and enabled, and is configured appropriately.
Create a new Systemd unit configuration file named graceful-shutdown.service and save it in the directory, /etc/systemd/system, where it is advised you put custom configuration files.
For example:
# vi /etc/systemd/system/graceful-shutdown.service
Enter the following text into the file, then save it:

Cloudflare has released a new rule as part of its Cloudflare Specials Rulesets, to protect our customers against a high-severity vulnerability in vBulletin.
A new zero-day vulnerability was discovered for vBulletin, a proprietary Internet forum software. By exploiting this vulnerability, bad actors could potentially gain privileged access and control to the host servers on which this software runs, through Remote Code Execution (RCE).
At Cloudflare, we use three key indicators to understand the severity of a vulnerability 1) how many customers on Cloudflare are running the affected software 2) the Common Vulnerability Scoring System (CVSS) score, and 3) the OWASP Top 10, an open-source security framework.
We assess this vulnerability to be very significant as it has a CVSS score of 9.8/10 and affects 7 out of the 10 key risk areas of the OWASP 2017 Top 10.
Remote Code Execution is considered a type of injection, which provides the capability to potentially launch a catastrophic attack. Through RCE an attacker can gain privileged access to the host server that might be running the unpatched and vulnerable version of this software. With elevated privileges the attacker could perform malicious activities including discovery of additional Continue reading

A long while ago Daniel Dib wrote a nice blog post on “SDN will make the networking engineers obsolete” theme. While it sounds like beating a dead horse, the SDN craze isn’t subsiding, so another healthy dose of common sense might come handy.
Hint: if you’re not following Daniel’s blog, you should… even though he decided to make old farts’ life harder by publishing on LinkedIn.
