Broadcom Sued by AT&T | The Gestalt IT Rundown: September 11, 2024

September 11, 2024

AT&T has decided enough is enough. They have filed a lawsuit over the tactics they claim are putting first responders and critical government services at risk. AT&T is claiming breach of contract because of the new support policy enacted by Broadcom after the VMware acquisition. The key point comes in an amendment in their support agreement that says that AT&T can renew their current support contracts for up to two more years provided they do so before the expiration of their current contract. They are exercising that option now but VMware by Broadcom is not honoring the renewal. AT&T stated they don’t have an issue with the business model change, just that it affects them right now and is making them pay more.

This move follows a very recent acquisition of Silo AI, which we covered on the Rundown, as well as their last big acquisition of Xilinx. There’s a lot to unpack here and the Futurum Group has had some amazing coverage of this deal so far. Stephen, let’s start with you. What does ZT Systems have that makes them so attractive to AMD.

Network as a Service is More of a Financial Model

August 6, 2024

Network-as-a-Service (NaaS) is a very popular topic in the modern enterprise. It promises a way to consume networking technologies in the same way that one would purchase cloud computing by only charging users for what they need.

Crowdstrike Update Strikes Microsoft’s Cloud Services | The Gestalt IT Rundown: July 24, 2024

July 24, 2024

You probably felt the pain this past Friday morning from a huge outage. No, not the one on Azure. A misconfigured update to popular security platform Crowdstrike took down over 8 million Windows PCs and servers. The configuration file caused the system to halt and refuse to boot. Affected entities included mulitple airlines, healthcare systems, and even Starbucks Order Ahead. Fixes were developed and put into play but they required a reboot to safe mode or mounting an image on a new system to remove the offfending file, which ground AWS to a halt over the weekend. Crowdstrike’s CEO released a statement that was not well received, especially because he was the CTO at McAfee when a simliar issue happened back in 2017.
