Ivan Pepelnjak has an interesting post up today about MacGyver-ing in the network. He and Simon Milhomme are right that most small-to-medium sized networks are pretty much non-reference architectures and really, really difficult to manage and maintain properly on the best of days. On the worst of days, they’re a nightmare that make you want to run screaming into the night. But why?
Part of the issue is that reference architectures and cookie-cutter designs aren’t made for SMEs. Sure, the large enterprise and cloud providers have their own special snowflakes. But so too do small IT shops that have been handed a pile of parts and told to make it work.
People like Greg Ferro and Peyton Maynard-Koran believe this is due to vendors and VARs pushing hardware and sales cycles like crazy. I have attributed it to the lack of real training and knowledge about networking. But, it also has a lot to do with the way that people see IT as a cost center. We don’t provide value like marketing. We don’t collect checks like accounting. At best, we’re no different than the utility companies. We’re here because we have to be.

Cybersecurity has become an integral part of any IT system. This course is focused on the 5 key elements of penetration testing: Information Gathering, Scanning, Enumeration, Exploitation, and Reporting. These key areas build upon each other and provide you with the technical know-how to gear you up for a career in penetration testing.
Who Should Watch:
This course is for students who want to become a penetration tester. It is recommended to have at least 3 years experiences with networking and basic security knowledge. Other cybersecurity certifications are always a help.
What You’ll Learn:
In this course you will learn the required skills to pass the CPTE demonstration practical knowledge of penetration testing and cybersecurity. At the end of this course you will have the understanding of the basic course requirements to pass the exam and conduct penetration tests.
About The Instructor:
Joe Brinkley has over 10 years of professional IT and Information Security experience under his belt. Joe has always been a tinkerer, geek and all around “computer guy.” He has numerous certifications including the CPTE.

Today we’re excited to announce the official GA of Rocket Loader, our JavaScript optimisation feature that will prioritise getting your content in front of your visitors faster than ever before with improved Mobile device support. In tests on www.cloudflare.com we saw reduction of 45% (almost 1 second) in First Contentful Paint times on our pages for visitors.
We initially launched Rocket Loader as a beta in June 2011, to asynchronously load a website’s JavaScript to dramatically improve the page load time. Since then, hundreds of thousands of our customers have benefited from a one-click option to boost the speed of your content.
With this release, we’ve vastly improved and streamlined Rocket Loader so that it works in conjunction with mobile & desktop browsers to prioritise what matters most when loading a webpage: your content.
To put it very simplistically - load time is a measure of when the browser has finished loading the document (HTML) and all assets referenced by that document.
When you clicked to visit this blog post, did you wait for the spinning wheel on your browser tab to start reading this content? You Continue reading
In addition to NSX, the company’s software-defined storage and hyperconverged products also saw strong growth during the first quarter of its fiscal 2019.
Believe it or not, Cisco Systems has a bunch of customers for its UCS blade and rack servers that are in the gaming industry, which has its share of near-hyperscale players who have widely geographically distributed clusters spread around the globe so players can get very low latency access over the Internet to games running on that infrastructure. …

The Cambridge Analytica data misuse is the most recent high-profile incident to impact Internet trust. Trust – or the lack thereof – is the term used to describe much of the current state of the Internet. For years now, we have been hearing about a decline in user trust because of fears of surveillance, cybercrime, data breaches, crack downs on speech, or misuse of their data.
However, recently updated data from a recently released edition of CIGI’s annual survey on Trust seems to shatter commonly-held views on the state of trust and raise some novel questions. While the survey covers a wide range of issues from privacy to e-commerce and online habits, one particular result is rather striking:
Three quarters of respondents (73%) said that they agree with the statement “overall, I trust the Internet.” Last year only 56% said that. The trust was highest in China (91%) and India (90%).
This result appears to contradict the assumption that overall trust in the Internet is diminishing.
If, indeed, there is an overall increase in trust, then the first question we should ask is: what type of trust are we talking about?
One challenge that every WISP owner or operator has faced is how to leverage unused bandwidth on a backup path to generate more revenue.
For networks that have migrated to MPLS and BGP, this is an easier problem to solve as there are tools that can be used in those protocols like communities or MPLS TE to help manage traffic and set policy.
However, many WISPs rely solely on OSPF and cost adjustment to attempt to influence traffic. Alternatively, trying to use policy routing can lead to a design that doesn’t failover or scale well.
WISPs that are OSPF routed will often have a primary path back to the Internet at one or more points in the network typically from a tower that aggregates multiple backhauls.
As more towers are added that rely on this path, it can create a bottleneck while other paths are unused.
One way to solve this problem is to use VLANs to create another subnet for OSPF to form an adjacency.
By tagging the VLAN from Tower 6 through Tower 3 and into Tower 4, a new path Continue reading
