Colocation provider Cyxtera Technologies has filed for Chapter 11 bankruptcy after spending the last few months trying to find a buyer or reduce its debt load. The company will now attempt to restructure through bankruptcy or perhaps a suitor will come along to buy out the company.

Meanwhile, the company says it will be business as usual for its customers, but with the reorganization that comes with Chapter 11, it’s hard to say whether that will last, according to Bill Kleyman, an independent consultant to data-center companies.

The reliability of services delivered by ISPs, cloud providers and conferencing services (a.k.a. unified communications-as-a-service (UCaaS)) is an indication of how well served businesses are via the internet.

ThousandEyes is monitoring how these providers are handling the performance challenges they face. It will provide Network World a roundup of interesting events of the week in the delivery of these services, and Network World will provide a summary here. Stop back next week for another update, and see more details here.

Semiconductors, especially CPUs, are immensely complex creations all done at the microscopic level. That there aren’t more bugs, for lack of a better word, is a testament to the efforts that these chipmakers put in to delivering solid products. But occasionally, something slips by.

AMD has issued an alert that an older processor line has a minor error. The problem exists in its Epyc 7002 line, code-named Rome, which was released three years ago. The bug, first noted on a Reddit thread, says that servers running Rome-era chips will hang after 1,044 days of uptime or nearly three years.

Software-defined networking (SDN) is a network management technique that centralizes control of network appliances in software. SDN makes network management easier in two ways: it allows networks to be administered as a whole, rather than on a device-by-device basis, and it allows for administrative work to be automated and conducted on the fly in response to changing network needs and conditions.

The first SDN system to gain traction was the open source OpenFlow protocol, which rolled out in 2011. There are now a number of possible SDN models, each providing significant benefits when compared to traditional networking.

There are always things to wait for on a Linux system—upgrades to complete, processes to finish, coworkers to log in and help resolve problems, status reports to be ready.

Fortunately, you don’t have to sit twiddling your thumbs. Instead, you can get Linux to do the waiting and let you know when the work is done. You can do this with a script or you can use the wait command, a bash built-in that watches for processes running in the background to complete.

Crafting waiting within scripts

There are many ways to craft waiting within a script. Here’s a simple example of simply waiting for a period of time before moving on to the next task:

Telecom ministers from at least 18 EU countries have rejected a proposal by network operators to have major technology companies fund the rollout of 5G and broadband.

The proposal, put forward by telecom lobbying groups GSMA and ETNO, which represent 160 operators across Europe, says that big tech companies that account for more than 5% of a provider’s peak average internet traffic should help foot the bill for rolling out the services across Europe.

The EU launched a consultation on the issue in February 2022. According to a report by Reuters, telecom ministers met with EU Commissioner Thierry Breton to raise their objections, with those who are against the proposal saying there is a lack of analysis to prove the measure would actually work, with some citing concerns that tech companies would end up passing these costs onto the consumer.

IT organizations that apply artificial intelligence and machine learning (AI/ML) technology to network management are finding that AI/ML can make mistakes, but most organizations believe that AI-driven network management will improve their network operations.

To realize these benefits, network managers must find a way to trust these AI solutions despite their foibles. Explainable AI tools could hold the key.

A survey finds network engineers are skeptical.

In an Enterprise Management Associates (EMA) survey of 250 IT professionals who use AI/ML technology for network management, 96% said those solutions have produced false or mistaken insights and recommendations. Nearly 65% described these mistakes as somewhat to very rare, according to the recent EMA report “AI-Driven Networks: Leveling Up Network Management.” Overall, 44% percent of respondents said they have strong trust in their AI-driven network-management tools, and another 42% slightly trust these tools.

Data center developers are under pressure to expand their horizons when it comes to choosing sites for new construction. Land prices, availability of power and bandwidth, and pushbacks from neighbors are among the factors that are driving developers to seek new regions.

Northern Virginia, for example, is home to more data centers than any other part of the world, with 275 and more on the way. But the region is running out of space and available power, and residents are running out of patience for these resource-intensive facilities that consume growing amounts of power and water, according to the Washington Post.

More than a year ago, Nvidia CEO Jensen Huang said he was open to the possibility of having Intel manufacture Nvidia’s GPUs through Intel's foundry services program.

At the time, Huang was noncommittal beyond saying that Nvidia was looking at the possibility. Now things are getting more concrete. During a question-and-answer session at the Computex tradeshow in Taipei, Taiwan, Huang said he had recently received good results for an Intel test chip based on the company's next-generation process node.

"You know that we also manufacture with Samsung, and we're open to manufacturing with Intel. [Intel CEO Pat Gelsinger] has said in the past that we're evaluating the process, and we recently received the test chip results of their next-generation process, and the results look good," Huang said.

A software-development team caused quite a stir recently with a blog post describing how it abandoned a serverless architecture project in favor of a monolith—and slashed cloud infrastructure costs by 90% in the process.

But this wasn’t just any team; the post was written by Marcin Kolny, a senior software-development engineer at Amazon Prime Video.

Since Amazon is one of the leading advocates for serverless computing, not to mention the market leader in cloud services, the post was viewed as either a commendable act of openness or the very definition of throwing your company under the bus. Either way, it triggered a passionate back and forth on social media platforms that focused on larger questions:

The convert command from the ImageMagick suite of tools provides ways to make all sorts of changes to image files. Among these is an option to change the resolution of images. The syntax is simple, and the command runs extremely quickly. It can also convert a image from one format to another (e.g., jpg to png) as well as blur, crop, despeckle, dither, flip and join images and more.

Although the commands and scripts in this post mostly focus on jpg files, the convert command also works with a large variety of other image files, including png, bmp, svg, tiff, gif and such.

Basic resizing

To resize an image using the convert, you would use a command like this:

Intel has announced a shift in strategy that impacts its XPU and data-center product roadmap.

XPU is an effort by Intel to combine multiple pieces of silicon into one package. The plan was to combine CPU, GPU, networking, FPGA, and AI accelerator and use software to choose the best processor for the task at hand.

That’s an ambitious project, and it looks like Intel is admitting that it can’t do it, at least for now.

Jeff McVeigh, corporate vice president and general manager of the Super Compute Group at Intel, provided an update to the data-center processor roadmap that involves taking a few steps back. Its proposed combination CPU and GPU, code-named Falcon Shores, will now be a GPU chip only.

It’s been 17 years and counting since Nemertes first wrote about the logic of integrating event response in the enterprise: bringing together the security operations center (SOC) and network operations center (NOC) at the organizational, operational, and technological levels. Needless to say, this has not happened at most organizations, although there has been a promising trend toward convergence in the monitoring and data management side of things. It’s worth revisiting the issue.

Why converge?

The arguments for convergence remain pretty compelling:

• Both the NOC and SOC are focused on keeping an eye on the systems and services comprising the IT environment; spotting and understanding anomalies; and spotting and responding to events and incidents that could affect or are affecting services to the business.
• Both are focused on minimizing the effects of events and incidents on the business.
• The streams of data they watch overlap hugely.
• They often use the same systems (e.g. Splunk) in managing and exploring that data.
• Both are focused on root-cause analysis based on those data streams.
• Both adopt a tiered response approach, with first-line responders for “business as usual” operations and occurrences, and anywhere from one to three tiers of escalation to more senior engineers, architects, and analysts.
• Most crucially: When something unusual happens in or to the environment (that router is acting funny), it can be very hard to know up front whether it is fundamentally a network issue (that router is acting funny – it has been misconfigured) or a security issue (that router is acting funny – it has been compromised) or both (that router is acting funny – it has been misconfigured and is now a serious vulnerability). Having fully separate NOC and SOC can mean duplicative work as both teams pick something up and examine it. It can mean ping-ponging incidents that bounce from one to the other, or incidents that neither picks up, thinking the other has or will.

At the very least, the lower tiers of separate NOC and SOC operations should be converged, so that there is neither duplication nor a game of hot potato as staff try to figure out what a problem actually is, and whether the response will be network focused, security focused, or both. Maintaining separate or semi-separate escalation paths is supportable given that lower-level convergence.

The US Commerce Department should put trade restrictions on Chinese memory chip maker Changxin Memory Technologies (CXMT), say lawmakers on the US House of Representative’s Committee on China.

The comments come in the wake of the Chinese government's ban on the use of some Micron chips in certain sectors, citing concerns that the products pose a significant security risk to the country’s key information infrastructure supply chain.

However, these claims are “not based in fact” White House press secretary Karine Jean-Pierre told reporters, adding that the Department of Commerce was engaged directly with the PRC (People's Republic of China) to detail the administration’s views on the ban.
