Cloudflare Workers Now Support COBOL
Recently, COBOL has been in the news as the State of New Jersey has asked for help with a COBOL-based system for unemployment claims. The system has come under heavy load because of the societal effects of the SARS-CoV-2 virus. This appears to have prompted IBM to offer free online COBOL training.
As old as COBOL is (60 years old this month), it is still heavily used in information management systems and pretty much anywhere there’s an IBM mainframe around. Three years ago Thomson Reuters reported that COBOL is used in 43% of banking systems, is behind 80% of in-person financial transactions and 95% of times an ATM card is used. They also reported 100s of billions of lines of running COBOL.
COBOL is often a source of amusement for programmers because it is seen as old, verbose, clunky, and difficult to maintain. And it’s often the case that people making the jokes have never actually written any COBOL. We plan to give them a chance: COBOL can now be used to write code for Cloudflare’s serverless platform Workers.
Here’s a simple “Hello, World!” program written in COBOL and accessible at https://hello-world.cobol.workers.dev/. It doesn’t do much--it Continue reading
Cisco to Offer Online Testing
Other vendors such as Juniper and AWS have already started doing it, now it’s Cisco’s turn to offer online testing. This is especially welcome in Covid times where it’s difficult to go visit an on-premises Pearson/Vue test center. Starting April 15, Cisco will offer remote testing and this means you can take your test any time, any day, around the year. Almost all of the written tests will be offered, including the DevNet ones! The CCDE is one of the excluded tests.
What is required to take the test online? There are some prerequisites:
- Quiet, private location
- Reliable device with a webcam
- Strong Internet connection
- OnVUE software
- Government-issued identification
Your test will be proctored by an online proctor. Before the test starts, you will need to show your room, that there are no books or notes, that you are alone in the room and that you can close the room etc. As well that you are not wearing a watch or have access to a mobile phone. You will also need to provide a valid ID before starting the test. If you break any rules, you will of course not receive a passing score. You can find more information in Susie Wee’s Continue reading
Growing Beyond Ansible host_vars and group_vars
One of the attendees of my Building Network Automation Solutions online course quickly realized a limitation of Ansible (by far the most popular network automation tool): it stores all the information in random text files. Here’s what he wrote:
I’ve been playing around with Ansible a lot, and I figure that keeping random YAML files lying around to store information about routers and switches is not very uh, scalable. What’s everyone’s favorite way to store all the things?
He’s definitely right (and we spent a whole session in the network automation course discussing that).
IPv6 Buzz 049: IPv6 and Renumbering
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.
What happened
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!
