If your internet connection seems slow, don’t blame the internet. It’s you. Or to put it more precisely, it’s the equipment in your house, or the service plan you have or the way your home connects to the broader internet network. Or all three.

Millions of people are teleconferencing for work or school. We’re streaming more movies and You Tube videos than ever before; so many that in Europe Netflix, Google, Disney and Amazon have throttled back their picture quality to conserve bandwidth.

Zoom, perhaps the most widely used video conferencing service, has seen its usage – excuse the expression – zoom. At the end of 2019, the company had 10 million daily users. At the end of March it had 200 million, which has exposed flaws, bugs and security issues.

Now not mostly just for business meetings, schools have embraced Zoom to hold online classes. Families and friends are logging on to socialize and to play games, many now being designed specifically for the service.

New York Times analysis suggests that with nearly all sporting events cancelled – marble racing an exception – gaming sites are seeing double digit increases. Gaming of all kinds across all platforms soared by 75% as of March 19, according to Statista.

All this gaming and video usage is placing a strain on the internet. While the broader network is handling the load, most local connections were not built to handle the demand. Where business centers have typically been upgraded with high speed, high bandwidth fiber, residential areas are most often connected over cable.

Cable was designed to deliver video, not upload it, so video conferencing from home – as most of us are now doing – is fraught with dropped connections and jerky video. This gets worse as more and more users are online at the same time.

In areas that have been upgraded, slowdowns are more likely to be the result of your equipment or how much bandwidth you’re paying for. Before everyone was home and online at the same time, basic internet service and equipment may have only rarely caused slowdowns. Older WiFi equipment was not designed to handle multiple simultaneous video or gaming users.

“Still, despite these niggles, the internet seems to be doing just fine,” says the MIT Technology Review . “Health checks from RIPE and Ookla, two organizations that monitor connection speeds around the world, show minor slowdowns but little change overall.”

“In fact,” notes the article, “Far from bringing networks to their knees, covid-19 is driving the most rapid expansion in years.”

The article explains that streaming and gaming services are adding capacity, while last mile providers like Comcast and AT&T are experimenting with changes to their plans and are looking at how to upgrade the cables and wires that bring internet service into our homes. Comcast lifted data caps for two months.

“Some of these measures may be undone when the crisis is over, but others will outlive it. Once cut, red tape is hard to stick back together.”

AI Chatbots Could Ease Demand on COVID-19 Hotlines

A solution to overtaxed COVID-19 hotlines could be only a chatbot away.

Researchers from the Indiana University Kelley School of Business found that when callers felt comfortable in the chatbot’s ability they considered the bot at least as good as a human.

“The primary factor driving user response to screening hotlines — human or chatbot — is perceptions of the agent’s ability,” said Alan Dennis, chair of internet systems at Kelley and corresponding author of the paper to be published in the Journal of the American Medical Informatics Association.

“When ability is the same, “he said, “Users view chatbots no differently or more positively than human agents.”

Noting that, as they write in their report, “The sudden unprecedented demand for [COVID-19] information is overwhelming resources,” Dennis and three other researchers set out to learn if people would use a chatbot and follow its advice. They presented text chats between callers and agents. Each study participant saw the same exact chat. Some were told the agent was a bot; others were told it was a human.

The researchers found the participants biased, believing the chatbots less able than a human agent. Those who trusted the provider of the chatbot service were more comfortable in the bot’s ability.

“The results show that the primary factor driving patient response to COVID-19 screening hotlines (human or chatbot) is users’ perceptions of the agent’s ability,” the researchers wrote. Driving that perception is the user’s trust in the provider of the screening hotline.

“A secondary factor for persuasiveness, satisfaction, likelihood of following the agent’s advice, and likelihood of use was the type of agent, with participants reporting they viewed chatbots more positively than human agents.”

“This positive response may be because users feel more comfortable disclosing information to a chatbot, especially socially undesirable information, because a chatbot makes no judgment,” they theorized.

To make hotline callers more comfortable and confident speaking with a chatbot, the researchers suggest the sponsoring organization develop “a strong messaging campaign that emphasizes the chatbot’s ability. Because trust in the provider strongly influences perceptions of ability, building on the organization’s reputation may also prove useful.”

Homeland Security Issues Windows Bug Alert

Tens of thousands – perhaps hundreds of thousands — of Windows 10 users are vulnerable to a “wormable bug” so serious it has been given the highest score possible of the Common Vulnerability Scoring System.

Although Microsoft issued a fix for the bug in March, Homeland Security’s Cybersecurity and Infrastructure Security Agency issued an alert warning of the potential risk to systems that have not installed the fix.

Commonly referred to as SMBGhost, the vulnerability in Windows 10 systems was recently shown to be exploitable. That could give hackers complete access to the computer and, because the vulnerability is considered “wormable,” the exploit code can spread throughout a network, infecting all connected Windows 10 systems.

By default, Windows 10 automatically checks and installs updates. Home and small business users should already have the patch installed. You can check by following the directions from Microsoft.

However, estimates of the unprotected PCs range from the tens of thousands into the hundreds of thousands. For these systems, the risk of being successfully attacked and having the exploit spread is what prompted the Homeland Security warning. The agency warned that “Malicious cyber actors are targeting unpatched systems.”

In 2017, a wormable bug lead to the WannaCry ransomware spread, which disrupted businesses, government and transportation, and in the UK forced hospitals to halt activities and even turn patients away. Microsoft had issued a patch for the hacking tools that had been developed and stolen from the National Security Agency, but millions did not install it, leading to the disruption and damages worldwide estimated in the billions.
