In this week's episode Ed, Scott, and Tom discuss one of IT networking's biggest challenges, IP renumbering, and how IPv6 impacts (and is impacted by) it. Anyone who's ever had to do a significant IPv4 renumbering project knows just how labor intensive and painful this process can be. Will it be easier with IPv6? If so, how and why?

Starting at 1531 UTC and lasting until 1952 UTC, the Cloudflare Dashboard and API were unavailable because of the disconnection of multiple, redundant fibre connections from one of our two core data centers.
This outage was not caused by a DDoS attack, or related to traffic increases caused by the COVID-19 crisis. Nor was it caused by any malfunction of software or hardware, or any misconfiguration.
As part of planned maintenance at one of our core data centers, we instructed technicians to remove all the equipment in one of our cabinets. That cabinet contained old inactive equipment we were going to retire and had no active traffic or data on any of the servers in the cabinet. The cabinet also contained a patch panel (switchboard of cables) providing all external connectivity to other Cloudflare data centers. Over the space of three minutes, the technician decommissioning our unused hardware also disconnected the cables in this patch panel.
This data center houses Cloudflare’s main control plane and database and as such, when we lost connectivity, the Dashboard and API became unavailable immediately. The Cloudflare network itself continued to operate normally and proxied customer websites and applications continued to operate. As Continue reading

In this episode hosts Roopa Prabhu and Brian O’Sullivan chat with Justin Betz about production grade automation and CI/CD workflows for continuous maintenance and deployment of your “infrastructure as code.” They also discuss how like any other software code, code to manage and automate your infrastructure (IAC) has to be maintained, fixed, withstand hardware and software upgrades — so how do you do that? Finally, the group talks about Open Source production quality automation code. Enjoy!

As the COVID-19 emergency continues to affect countries and territories around the world, the Internet has been a key factor in providing information to the public. As businesses, organizations and government agencies adjust to this new normal, we recognize the strain that this pandemic has put on the groups working to assist in virus mitigation and provide accurate information to the general public on the state of the pandemic.
At Cloudflare, this means ensuring that these entities have the necessary tools and resources available to them in these extenuating circumstances. On March 13, we announced our Cloudflare for Teams products will be free until September 1, 2020, to ensure Cloudflare users and prospective users have the tools they need to support secure and efficient remote work. Additionally, we have removed usage caps for existing Cloudflare for Teams users and are also providing onboarding sessions so these groups can continue business in this new normal.
As a company, we believe we can do more and have been thinking about ways we can support organizations and businesses that are at the forefront of the pandemic such as health officials and those providing relief to the public. Many organizations have reached out to Continue reading

Derek Campbell joins Day Two Cloud for a discussion about DevOps. Of course, DevOps has been discussed to death across the IT landscape, so we drill into specifics with Derek to get his unique take, which he delivers with a Scottish accent. Even if you can't make out what he's saying, you've love listening to him.

Let’s agree for a millisecond that you can’t find any other way to migrate your workload into a public cloud than to move the existing VMs one-by-one without renumbering them. Doing a clumsy cloud migration like this will get you the headaches and the cloud bill you deserve, but that’s a different story. Today we’ll talk about being clumsy the right and the wrong way.
There are two ways of solving today’s challenge:
