After this date, chatting will no longer be available, and users have just six months to download their chat histories. At the moment, there is no direct replacement for Yahoo Messenger, but users are being advised that they can request an invite for the beta version of the invite-only group messaging app Yahoo Squirrel.

MyHeritage, which allows users to set up family trees and probe their DNA for clues about their ancestry, promptly reported the breach in a blog post.

Discovery of the breach falls on the heels of news that law enforcement used a different genealogy site to track down a long-sought suspect in the Golden State Killer case. Though investigators used publicly-available genetic data in that case, it opened widespread security and privacy concerns surrounding such ancestry-tracking and DNA testing sites, which have exploded in popularity recently.

Whois, which is used by the police and journalists to check the legitimacy of websites, no longer displays the name, email address or phone number of some websites.

In a letter to the Wall Street Journal entitled, The EU's gift to Cybercriminals, lawyers Brian Finch and Steven Farmer claim: "Police will be robbed of ready access to vital data drastically impeding their efforts to identify and shut down illicit activity."

Some of YouTube's most popular stars have criticised the website for "experimenting" with how their videos are delivered to their fans.

Technology vlogger Marques Brownlee - who has more than six million subscribers - said prioritising videos "they think we want to see" was a "business move". But he added: "It's a subscription box. Users chose to subscribe. They want to see it all. If they don't, they'll unsubscribe."

A few years back, Mark started making electronics repairs for his fellow college students and ordered parts from Amazon. He'd return items that were the wrong parts or defective, but sometimes would send back stuff he'd ordered extra of and didn't need anymore.

A few months later, he got another email from the same address with some sharper wording: "While we expect occasional problems with orders, such large numbers of returns can suggest that customers are unaware of our return policies.

He set up an account with a different name, email and shipping address, and added a VPN to his computer to hide his IP address. He was back up and running on the site.

"I asked you six 'yes' and 'no' questions, and I got not a single answer," said Guy Verhofstadt, a Parliament member representing Belgium. "Yes," someone in the room echoed in support. Others chimed in.

"I'll make sure we follow up and get you answers to those," Zuckerberg said, deferring to his team to provide more complete responses, just as he did with Congress in April.

In fact, nearly seven years after the eternally optimistic World IPv6 Launch launched, we are still only at just over a quarter availability of the new internet protocol.

As one avid IPv6 watcher – chief scientist of regional internet registry APNIC, Geoff Huston – has identified, the last four months of stats show a significant slowdown of IPv6 adoption.

The company's high-speed internet plan showed a data limit of 150GB, while its high-speed internet enhanced plan had a limit of 250GB, according to a Thursday report by consumer group Stop the Cap.

"The purpose of the trial was more the idea of accurately collecting and displaying usage in billing."

Back in February, Google announced its plans to label all sites accessed over regular unencrypted HTTP as "not secure," starting in July. Today, the company described the next change it will make to its browser: in September, Google will stop marking HTTPS sites as secure.

Most HTTP sites will get a regular gray "Not secure" label in their address bar. If the page has user input, however, that gray label will become red, indicating the particular risk the page represents: Web forms served up over HTTP could send their contents anywhere, making them risky places to type passwords or credit card numbers.

Snapchat began testing the new ad format -- first spotted by AdAge -- in the US on Monday. These unskippable video ads, aka commercials, are only running in Snapchat Shows, not across the entire app.
