Not one, not two, but three undersea cables cut in Jersey
Sometime before midnight Monday (UK local time) a ship dropped its anchor and broke, not one, not two, but three undersea cables serving the island of Jersey in the English Channel. Jersey is part of the Channel Islands along with Guernsey and some smaller islands.

These things happen and that’s not a good thing. The cut was reported on the venerable BBC news website. For the telecom operators in Jersey (JT Global) this wasn’t good news. However looking at the traffic from Cloudflare’s point of view; we can see that while the cable cut removed the direct path from London to Jersey, it was replaced by the backup path from Paris to Jersey. The move was 100% under the control of the BGP routing protocol. It's a relief that there's a fallback for when these unpredictable events happen.
Here's a look at one network on the island.
The red traffic is being served from our London data center (the normal location for all Jersey traffic) and the blue traffic is coming from our Paris data center. The step could well be caused by either a delayed break in one of the cables or the Continue reading

Netbox IPAM/DCIM – What all Network Engineers beg for!
We found it!!!
Have you ever sat at your desk, hoping on a miracle, that somebody somewhere will develop a fully comprehensive application for tracking network information??? I know I have, along with millions of other fellow network professional’s I have to assume. What exactly am I referring to? IP addresses, vlans, VRF’s, Rack Elevations and on and on and on. We all have to keep up with this information, for most it is located in spreadsheets; some in notepads; others try to lock it all away in the vast empty space we call a brain.
So, the stage is set. Yes, there are claims of applications that can keep track of what your CORE router IP address is and what vlan you assigned to one of your customers, or even where in the bloody rack it sits in relation to your other devices. Some can even keep track of which VRF routing table your management lies in along with which physical port it connects to. Going a little further, maybe the application claims to give you a basic map layout to which you can refer to…
BUT, very few paid applications actually combine most of these functions into one and very Continue reading

Tips for building SD-WANs
The substantially high cost of MPLS circuits ($200-$400/Mbps/month) compared to easily deployed, lower cost broadband Internet (with a price tag of $1/Mbps/month) has triggered a shift in enterprise architectures to the software defined WAN. SD-WAN provides the flexibility to choose the most optimal transport and dynamically steer traffic over a mix of MPLS circuits, the public Internet, or even wireless LTE circuits.
The access transport selection depends on a variety of factors, including the type of application, traffic profile, security requirements, QoS and network loss and latency. When implemented correctly, SD-WAN truly has significant advantages: Faster service deployment, increased flexibility, unified management and improved application performance, to name a few. But, while familiarity about SD-WAN has increased over the last year, a survey by Silver Peak and IDG shows only 27% of small- to mid-sized enterprises have shifted to SD-WAN.

Isolation technologies create an “air gap” to eliminate the risk of malware
This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.
Like the threat landscape itself, web gateways have changed over the years. Back in the 1990s, organizations primarily used them to prevent employees from wasting time surfing the web – or worse, from visiting gambling, adult and other unauthorized websites. Today web gateways do much more than enforce regulatory compliance and HR policies. Whether they are implemented on-premise or as cloud-based services, organizations rely on web gateways to thwart Internet-borne threats delivered through users’ browsers.
