  3. A timely post.

    I'm with Plusnetr and am experiencing exactly the same problem.
    Some interenal links in some sites I already had loaded still
    work but most do not.


    Which, as seems to be confirmed on the "plusnet.services.customer.
    feedback" NG seemks to be a p[roblem with the Pliusner D.N.S server

    Which might be worked around if someone helpfuly posted some numerical
    adresses for Google BBC etc which could be used in the meantime ?

    Plusnet have tweeted that there is 'a service outage' and are
    'investigating'.
    https://twitter.com/plusnethelp

    We have no internet at home either and their status page is not responding.

    It's fixed now - at least internet connectivity is working for us.

    The plusnet homepage is still down, though.

    8.8.8.8 is correct, but 4.4.4.4 is misremembering of google's 8.8.4.4
    and level3's 4.2.2.2

    It seems Google have "subbed" 8.8.8.0/24 and 8.8.4.0/24 from level3 who
    own 8.0.0.0/8

    And that is where the problem lies, Level 3. They seem to have been
    guilty of a widespread batch misconfiguration of network
    routing/withching hardware, and the world and his wife are affected.

    See, for example:
    https://www.reddit.com/r/networking/comments/3imwrc/level_3_internet_outage/

    Longer ago than I care to admit to remembering, but I will it admit
    that it was before the days of renting cloud-space as now, I was one
    of several regional IT staff in a large financial organisation who
    were repeatedly kept late at work while a particular 'expert' in
    London tried to upgrade our routing hardware remotely. The last and
    final failure kept us past 10 pm, and I had a 50+ mile drive home. The
    first thing I did when back at work next morning was to email all the
    other people involved saying: "Jeez, it's morning, I must've fallen
    asleep in the equipment room!". Apparently this caused widespread
    hilarity ... to everyone except the 'expert'!

    I think that 'expert' has bred and the offspring followed his/her line
    of work :-(

    Is there such a word? Perhaps I ought to disable spell-checking on my
    news-prog, I'm sure my original typo was a lot closer. Anyway,
    hopefully it's clear that I meant ...

    Yes my former employer (ICL) had separate public addresses for every
    employee, rather than a single public address that was mapped by NAT in the
    router to the employee's IP address. We had to hard-code the IP address into
    the PC's TCP config because they didn't have DHCP.

    It was so much easier on internal private development LANs that we set up
    from time to time because we had our own router and could configure it to
    allocate IP addresses automatically with "this newfangled DHCP".

    Still it was better than the early days when we used OSLAN and the changing
    the config details (roughly the equivalent of IP address, gateway address
    and DNS server) required a reboot :-(

    Same experience for me on Plusnet. I lost Google and Amazon for some
    time in the early hours, although Facebook and Bing were working fine.
    All seem to be back now.

    I got my internet working by inputting the Open DNS.

    No doubt Plusnet will be ok again is there any reason not to stay with Open
    DNS or Googles DNS?

    Are security issues or speed issues?

    Potentially, the issue is privacy; neither Cisco or Google are providing
    DNS services from the goodness of their heart ...

    Just set your DNS servers to 8.8.8.8 and 8.8.4.4 (google's own public
    DNS servers) and all will be well.

    Sadly, using the IP address for news.bbc.co.uk did not work - it was the
    first thing I tried: anticipating occasional DNS failures I have a list of a
    few commonly-accessed sites and their IP addresses. If a site failed to open
    when referenced by its URL or if the URL was pinged, then it also failed to
    open or to respond to ping when referenced by its IP address.

    This makes me think that it was not simply a DNS server that failed at
    Plusnet but something involved in routing traffic.

    Curiously, when I changed my router's DHCP to allocate a Google or OpenDNS
    DNS server address rather than Plusnet's, the ability to ping an affected
    site by IP address returned. If it had been a simple DNS failure, I'd still
    have been able to ping by IP, even without tweaking my router.

    Very weird.

    So do I, but you still need to put an upstream one (or more) to
    forward DNS queries that can't be resolved locally, if only to reduce
    load on the root level servers.

    And using a local DNS can actually make it more difficult to diagnose
    that kind of problem, as some "external" queries will be resolved from
    the cache on the local DNS, while some won't be there - which is a
    good reason not to run local DNS unless you know what you are doing.

    I forward to OpenDNS, as it gives a good level of basic filtering, and
    I have kids in the household.

    I was unable to connect to the Internet using Plusnet. It was not a DNS
    problem for me as I use OpenDNS. I suppose that the PN infrastructure
    could have had DNS issues but it looked more serious than that.
