    Amongst all root servers instances in India, seems like F-Root server by @iscdotorg has most locations, in total 15 locations. All major cities are covered.

    See root-servers.org/ (scroll down and click F) to see locations.

    @jpmens Just guessing here but as the file actually has a Bind DB format, perhaps it’s handler remains open (as long as #Bind9 is running) and is just written to.
    What happens when Bind is stopped/restarted?
    Certainly @ondrej or anyone at @iscdotorg can most confidently reply.

    Read this: it was cosigned by @nlnetlabs

    Hopefully the @EUCommission will be listening.

    For anyone interested in using Kea DHCP server on buildroot, I have submitted a new package patch that is currently awaiting upstream review. You can check it out here:

    As I was cleaning out my home office I found this relic. Published in 2001 and as the cover says it covers Bind 9, to be more specific Bind 9.1. Today, Bind is at version 9.18, released in 2020. It shows you that software that was written well does not need tons of updates. #DNS #SystemsAdministration @iscdotorg

    CW: New multi-implementation DNSSEC validation DoS vulnerabilities - CVE-2023-50387 ("KeyTrap"), CVE-2023-50868 (NSEC3 vuln)

    (living doc, updated regularly - if you prefer a low-edit post to boost, use infosec.exchange/@tychotithonu)

    Looks like DNS-OARC coordinated fixes in advance, but no centralized analysis at first other than the announcement from the team who discovered KeyTrap:

    Details may be still partially embargoed until patching ramps up.

    Analysis:

    DoS of all major DNSSEC-validating DNS resolvers (servers, but also maybe local resolvers like systemd's?) at the implementation level. Exploitation described as 'trivial'. Both are CVSS 7.5. DNS is a rich ransom target - but some resolver setups don't even validate DNSSEC.

    "In 2012 the vulnerability made its way into the implementation requirements for DNSSEC validation, standards RFC 6781 and RFC 6840" (per ATHENE)

    Per the Unbound writeup, both vulns require query to a malicious zone (which is probably not hard to trigger, for any DNSSEC-enabled client or server).

    Resolution: patch (recommended); disable DNSSEC validation (discouraged, but can buy you time / mitigate active DoS)

    Fixes mitigate the exhaustion by putting caps on validation activities. These caps appear to have been missing from most implementations.

    Details:

    Two DNSSEC DoS CVEs:

    CVE-2023-50387 ("KeyTrap"): "DNSSEC verification complexity can be exploited to exhaust CPU resources and stall DNS resolvers" (CVSS 7.5)
    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
    seclists.org/oss-sec/2024/q1/1

    (KeyTrap was discovered by ATHENE - their press release here has very important detail:
    athene-center.de/en/news/press)

    CVE-2023-50868: "NSEC3 closest encloser proof can exhaust CPU" (CVSS 7.5)
    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

    Sorry for the delay in replying! Let’s be clear upfront: we can’t build a fully operational space elevator with today’s technology.

    But history shows us that what seems impossible today can become reality tomorrow. When President John F. Kennedy set the goal of landing a man on the Moon in 1961, many thought it was a pipe dream. Yet less than a decade later, the Apollo program succeeded, proving that with determination, innovation, and investment, the impossible can be achieved. So, while ambitious, a space elevator is a plausible future project.

    Trying to be as objective as I can, here’s a more nuanced take on feasibility — starting with economics. A space elevator would be expensive; estimates vary, but it’s safe to say it would be a multi-billion-dollar project. To put that in perspective: SoFi Stadium cost $4.9 billion, and the Apollo program cost about $203 billion (adjusted to 2015 dollars). Expert analyses estimate the cost of the first space elevator between $6 billion and $100 billion depending on design and infrastructure included. So financially, it’s ambitious but plausible, especially as a long-term infrastructure investment with transformative potential for space access and sustainable resource use.

    The technical challenges are immense, but so are those of every large, unprecedented undertaking. Picture a tether anchored to a mobile ocean platform, gently swaying with the waves, while robotic climbers ascend and descend, carrying cargo and passengers to the stars.

    Several organizations, including the International Space Elevator Consortium, are actively developing the technologies and infrastructure needed. While we’re far from the finish line, the potential benefits—significantly reduced launch costs, increased space access, and large-scale space-based solar power—are exciting.

    A key technical hurdle is finding a material with sufficient tensile strength. Though it might sound counterintuitive, a space elevator is more like a suspension bridge to space than a giant tower. The concept evolved from building “bottom-up” to a “top-down” approach, where a geostationary satellite deploys a cable down to Earth. Currently, carbon nanotubes (CNTs) and ultra-high molecular weight polyethylene (UHMWPE) are leading candidates for tether materials. For example, Shizuoka University in Japan is prototyping and testing high-tensile-strength materials in space. The key issues remain: producing suitable materials like carbon nanotubes at scale.

    In conclusion, while we can’t build a fully operational space elevator today, overcoming the technical difficulties in the near future is possible. With continued advances in materials science, engineering, and technology, we may soon see the space elevator shift from futuristic fantasy to game-changing reality.

    I’m no space engineering expert, so I welcome corrections and insights.

    Several organizations, including the International Space Elevator Consortium, are actively developing the technologies and infrastructure needed. While we’re far from the finish line, the potential benefits—significantly reduced launch costs, increased space access, and large-scale space-based solar power—are exciting.

    A key technical hurdle is finding a material with sufficient tensile strength. Though it might sound counterintuitive, a space elevator is more like a suspension bridge to space than a giant tower. The concept evolved from building “bottom-up” to a “top-down” approach, where a geostationary satellite deploys a cable down to Earth. Currently, carbon nanotubes (CNTs) and ultra-high molecular weight polyethylene (UHMWPE) are leading candidates for tether materials. For example, Shizuoka University in Japan is prototyping and testing high-tensile-strength materials in space. The key issues remain: producing suitable materials like carbon nanotubes at scale.

    In conclusion, while we can’t build a fully operational space elevator today, overcoming the technical difficulties in the near future is possible. With continued advances in materials science, engineering, and technology, we may soon see the space elevator shift from futuristic fantasy to game-changing reality.

    I’m no space engineering expert, so I welcome corrections and insights.

    Our partner organisation, the British Interplanetary Society, is proud to support the 2026 International Space Competition, inviting young people aged 12–19 to design a “Martian Gateway” – a space station in orbit around Mars that links Earth, the Moon and a future Mars base.

    The competition is free to enter for individuals or teams of up to three, with major prizes including scholarships and STEM course places. Entries are open worldwide until 31 May 2026.

    Find full details and registration via the Arts & Business College of London, follow this link : abclondon.org.uk/programmes/st

    Could your Gateway concept include a #SpaceElevator to the Mars surface ? That's for you to decide !
