This article was originally posted on Packet Pushers Ignition on April 26, 2021. Data center virtualization exacerbated problems for network security designs that relied on a handful of appliance-based (whether physical or virtual) control points, which typically focused on external threats. With advanced persistent threats (APTs) that focus on compromising internal systems, security strategies must […]

In recent years we have witnessed an explosion of Internet-connected applications. Whether it is a new mobile app to find your soulmate, the latest wearable to monitor your vitals, or an industrial solution to detect corrosion, our life is becoming packed with connected systems.
How is the Internet changing because of this shift? This blog provides an overview of how Internet traffic is evolving as Application Programming Interfaces (APIs) have taken the centre stage among the communication technologies. With help from the Cloudflare Radar team, we have harnessed the data from our global network to provide this snapshot of global APIs in 2021.
The huge growth in API traffic comes at a time when Cloudflare has been introducing new technologies that protect applications from nascent threats and vulnerabilities. The release of API Shield with API Discovery, Schema Validation, mTLS and API Abuse Detection has provided customers with a set of tools designed to protect their applications and data based on how APIs work and their challenges.
We are also witnessing increased adoption of new protocols. Among encryption protocols, for example, TLS v1.3 has become the most used protocol for APIs on Cloudflare while, for transport protocols, we Continue reading
Got into an interesting BGP discussion a few days ago, resulting in a wild chase through recent SRv6 and BGP drafts and RFCs. You might find the results mildly interesting ;)
BGP has three dimensions of address family configurability:
Aaron Glenn sent me his thoughts on hardware differences between routers and switches based on the last paragraph of Dmytro Shypovalov’s views on the topic
To conclude, what is the difference between routers and switches in my opinion? I have absolutely no idea.
On today’s Tech Bytes podcast, sponsored by Palo Alto Networks, we’re going to talk about how a SASE architecture and a next-generation CASB, or Cloud Access Security Broker, can help security teams manage SaaS risks.

Take a Network Break! This week we examine the drivers behind Microsoft's proposed $68.7 billion acquisition of gaming company Activision Blizzard, Juniper integrates its SD-WAN portfolio with Mist Cloud, and Wi-Fi 7 emerges on the horizon. Cisco announces a new Catalyst switch for industrial use cases, Telia Carrier rebrands, and JP Morgan Chase discloses tidbits about its IT strategy.

We’re introducing new capabilities to help our customers prepare for upgrading to the latest releases — now available with NSX-T Data Center 3.2.0.1.
To ensure that existing NSX deployments can be successfully upgraded to NSX-T Data Center 3.2.x, we have provided an NSX Upgrade Evaluation Tool that operates non-intrusively as a separate downloadable tool to check the health and readiness of your NSX Managers prior to upgrade. Using NSX Upgrade Evaluation Tool can help avoid potential upgrade failures and save time by avoiding a rollback from a failed upgrade.
Customers upgrading to NSX-T 3.2.x are strongly encouraged to review the Upgrade Checklist and run the NSX Upgrade Evaluation Tool before starting the upgrade process.
In what follows, we’ll go over the details of the NSX Upgrade Evaluation Tool:
The main component of the NSX Upgrade Evaluation Tool is the database where a copy of NSX objects will be stored. The tool starts by making a secure copy of the database from an existing NSX Manager Continue reading
The early hours of Sunday, January 23, 2022, started in Burkina Faso with an Internet outage or shutdown. Heavy gunfire in an army mutiny could be related to the outage according to the New York Times (“mobile Internet services were shut down”). As of today, there are three countries affected by major Internet disruptions — Tonga and Yemen are the others.
Cloudflare Radar shows that Internet traffic dropped significantly in the West African country after ~09:15 UTC (the same in local time) and remains low more than 24 hours later. Burkina Faso also had a mobile Internet shutdown on January 10, 2022, and another we reported in late November 2021.
The main ISPs from Burkina Faso were affected. The two leading Internet Service Providers Orange and FasoNet lost Internet traffic after 09:15 UTC, but also Telecel Faso, as the next chart shows. This morning, at around 10:00 UTC there was some traffic from FasoNet but less than half of what we saw at the same time in preceding days.
It’s not only mobile traffic that is affected. Desktop traffic is also impacted. In Burkina Faso, our data shows that mobile devices normally represent 70% of Internet traffic.
With the Burkina Continue reading
