Explosions Rock London's Transport System

Filed under
Sci/Tech

A series of about six explosions rocked London's public transport system Thursday morning, killing at least two people and injuring others. Mobile and fixed-line telephone networks were severely congested as panicked Londoners called relatives in the city, but there were no initial reports of more widespread communications damage.

The cause of the explosions, which tore through a double-decker bus, an underground station and other locations, was not known early Thursday afternoon, although Britain's Prime Minister Tony Blair said the incidents appeared to be the work of terrorists.

London's public transport system was brought to a halt, with all Underground stations and bus routes closed, according to several reports.
Representatives from local operators Orange, O2 (UK), T-Mobile UK, Vodafone, and British Telecommunications all said they appeared to have suffered no damage to their infrastructure.

"Our network is not damaged but we are experiencing a high volume of traffic, forcing customers to dial numbers a few times before they get a connection," a Vodafone spokesperson says. "We're telling them they can expect some delay but they should keep trying."

Orange spokesperson Sarah Taylor says: "No U.K. mobile phone operators have infrastructure in the tube, so there are no base stations that can be affected in the Underground system. "We have taken action to ensure maximum availability and improve traffic flow on our network in the London area."

BT saw a big surge in call volumes, congesting its networks and leading to delays in calls getting through, a spokesperson says.
"We're asking people to only make essential calls," he says.

The news Web site of the British Broadcasting Corp., the state TV and radio company, continued to provide updates on events, although the site was slower to load than usual.

The main BBC Web site at www.bbc.co.uk, which usually carries information about TV programs and entertainment, was unavailable for part of the morning. It came back online around midday in a slimmed-down form, with news headlines relating to the explosions and a warning not to call emergency services except in life-threatening situations.

There was no noticeable variation in the volume of Internet traffic through The London Internet Exchange (Linx), which manages peering points in London for all major U.K. ISPs.

"With the Internet, there's been no effect," says Vanessa Evans, a spokesperson for Linx, adding, "There's a lot of traffic flowing to the news sites, which are holding up very well."

  • Webroot antivirus goes bananas, starts trashing Windows system files
    Webroot's security tools went berserk today, mislabeling key Microsoft Windows system files as malicious and temporarily removing them – knackering PCs in the process. Not only were people's individual copies of the antivirus suite going haywire, but also business editions and installations run by managed service providers (MSPs), meaning companies and organizations relying on the software were hit by the cockup. Between 1200 and 1500 MST (1800 and 2100 UTC) today, Webroot's gear labeled Windows operating system data as W32.Trojan.Gen – generic-Trojan-infected files, in other words – and moved them into quarantine, rendering affected computers unstable. Files digitally signed by Microsoft were whisked away – but, luckily, not all of them, leaving enough of the OS behind to reboot and restore the quarantined resources.
  • How The Update Framework Improves Security of Software Updates
    Updating software is one of the most important ways to keep users and organizations secure. But how can software be updated securely? That's the challenge that The Update Framework (TUF) aims to solve. Justin Cappos, assistant professor at New York University, detailed how TUF works and what's coming to further improve the secure updating approach in a session at last week's DockerCon 17 conference in Austin, Texas. Simply using HTTPS and Transport Layer Security (TLS) to secure a download isn't enough as there have been many publicly reported instances of software repositories that have been tampered with, Cappos said.

  • Malware Hunts And Kills Poorly Secured Internet Of Things Devices Before They Can Be Integrated Into Botnets
    Researchers say they've discovered a new wave of malware with one purpose: to disable poorly secured routers and internet of things devices before they can be compromised and integrated into botnets. We've often noted how internet-of-broken-things devices ("smart" doorbells, fridges, video cameras, etc.) have such flimsy security that they're often hacked and integrated into botnets in just a matter of seconds after being connected to the internet. These devices are then quickly integrated into botnets that have been responsible for some of the worst DDoS attacks we've ever seen (including last October's attack on DYN).

  • The Way GNOME Handles Wallpapers Really Annoys Me
    I love GNOME Shell — and no, not just because I’ve little choice now that is Ubuntu’s default desktop!

Like the following appreciably niche niggle in the the way GNOME handles desktop wallpapers.

Sarah sat down with me at CloudNativeCon in Berlin at the end of March to discuss both the Kubernetes community and open source communities more broadly. Among the topics we covered in the podcast were the challenges inherent in shifting from a company-led project to a community-led one, principles that can lead to more successful communities, and how to structure decision-making.

  • How to make branding decisions in an open community
    On April 18, Docker founder Solomon Hykes made a big announcement via a pull request in the main Docker repo: "Docker is transitioning all of its open source collaborations to the Moby project going forward." The docker/docker repo now redirects to moby/moby, and Solomon's pull request updates the README and logo for the project to match. Reaction from the Docker community has been overwhelmingly negative. As of this writing, the Moby pull request has garnered 7 upvotes and 110 downvotes on GitHub. The Docker community is understandably frustrated by this opaque announcement of a fait accompli, an important decision that a hidden inner circle made behind closed doors. It's a textbook case of "Why wasn't I consulted?"

Ubuntu 17.04: Unity's swan song?

For the most part, not much has changed on Ubuntu's Desktop edition in the past year. Unity 7 has more or less remained the same while work was progressing on the next version of the desktop, Unity 8. However, now that both desktops are being retired in favour of the GNOME desktop, running Ubuntu 17.04 feels a bit strange. This week I was running software that has probably reached the end of its life and this version of Ubuntu will only be supported for nine months. I could probably get the same desktop experience and most of the same hardware support running Ubuntu 16.04 and get security updates through to 2021 in the bargain. In short, I don't think Ubuntu 17.04 offers users anything significant over last year's 16.04 LTS release and it will be retired sooner. That being said, I could not help but be a little wistful about using Unity 7 again. Even though it has been about a year since I last used Unity, I quickly fell back into the routine and I was once more reminded how pleasant it can be to use Unity. The desktop is geared almost perfectly to my workflow and the controls are set up in a way that reduces my mouse usage to almost nothing. I find Unity a very comfortable desktop to use, especially when application menus have been moved from the top panel to inside their own windows. While there are some projects trying to carry on development of Unity, this release of Ubuntu feels like Unity's swan song and I have greatly enjoyed using the desktop this week. While there is not much new in Ubuntu 17.04, the release is pretty solid. Apart from the confusion that may arise from having three different package managers, I found Ubuntu to be capable, fairly newcomer friendly and stable. Everything worked well for me, at least on physical hardware. Unity is a bit slow to use in a virtual machine, but the distribution worked smoothly on my desktop computer. Read more
