    Exclamation FDCPS Severe Outrages thread

    **** CONNECTION DETAILS IN THIS THREAD ARE NOT CURRENT ****
    *** PLEASE REFER TO THE "How to get started thread" > here < ****


    COMPLETED - Planned outage 14-15 nov

    There will be a planned outage of the FDCPS project server at the end of this week. 14-15 NOV.

    The purpose of the outage is to relocate the project to a new server.

    Preparations have been made to make this as simple for the participants as possible.

    If your llrnet client config file is addressing the server as 'primesearch.free-dc.org' then you should not need to change anything.

    In order to minimise any errors we have shortened the knpairs file on IB-7773.
    The pairs that have been removed are ready for your clients on the new server.
    IB-7773 will be run dry (ETA 13 NOV), allowing your clients to empty their cache and the server to capture the last of the results from that port.

    At that point your client will become idle.

    Just leave your client running and when the DNS change is complete, it will resume normally.

    Once the project DNS change is implemented your client will begin picking up new work from the new server.

    The project DNS change may take 24-48 hours depending on the rate of refresh of the DNS cache of your ISP.

    Exceptions:
    1) If the client config is set up to address the server by the IP address, you should change it to the project server name instead 'primesearch.free-dc.org'.
    (Refer to the "How to get started" thread)
    2) If you are running the client under Unix/Linux and have added the project server to your hosts file you will need to update your hosts file with the new IP address.
    3) If you run a local DNS server / cache you may wish to force a DNS update


    Any changes to this release will be posted here.

    Thank you for your patience during this change.

    The transition occurred a bit earlier than planned.
    The DNS cascade was much faster than expected.

    Examining the transfer rates per participants per hour it looks like all clients carried across without a hitch.

    The stats export from the new server yesterday did not cantain some data from the old server leading up to the transition. This resulted in a 'negative' stats update for some participants. However, the new server has now been updated with the data from the old server and the stats export has made up the difference, returning the stats to the normal and correct values.

    Because of unexpected the speed of the DNS cascade, some pairs were left unprocessed on IB-7773. Those pairs have been made available on PCZ-7774 for clean-up.

    Cheers to PCZ, Bok and Beyond for the help in the transition.

    That pretty much concludes the transition.

    Thank you for your patience.


    A very special "Thank You" to Ironbits for the incentive, inspiration, ideas and infrastructure that got FDCPS to where it is.
    He's a Champion!

    Yup, everything seems to switch over pretty well, except that the new server still isn't handing out many primes...

    I'm only running an x58 with 8 instances but I keep a small cache so nothing was even noticed. Congrats to the squad for a succesful, not too? stressful move. All your work is appreciated, especially IB for getting me into it, even if he is on sabbatical or retired . Can't stay on holiday for ever bud, come back soon cos I actually miss you.....
    My lowly thanks to AMDave, and the usual crew of Bok,Pcz and Beyond for your tireless work on behalf of Free-DC and DC in general. Dunno where you guys find the time and energy cos I'm retired and I can't find any of either
    Like an ol` 8086, slow but serviceable.

    FDCPS Project is back on-line

    /ed- Thread title updated to reflect new status. See thread posts below -ed/

    The FDCPS Project is currently offline.
    The outage was planned to relocate to an alternate host.
    However the new server is experiencing an unplanned connectivity issue that may take a day or two more to be resolved.
    Further information will be posted when available.

    Update - Progress is being made
    The broadband connection has been restored.
    Middle-ware upgrades are in progress and dynamic testing is in progress.
    I'll update next when access will be restored.

    lots happening.
    migrated the site from 32 bit arch to 64 bit arch to take full advantage of 8GB ram
    moved to a different and slightly faster OS distro
    upgraded all middleware to current stable versions and latest patches
    that forced more than a few code changes to the web site and server scripts
    re-factored a lot of code while going through the spaghetti
    retired ChartDirector and introduced ajax flot charts
    most of the bugs are knocked out
    located a port 80 block in the WAN that "is not supposed to exist" and worked around it
    just a couple more issues (2, I think) to work through before we can resume this crunch-fest
    after that, tuning and miscellaneous bug fixes will resume in the background
    back soon ...

    LAN and MAN testing completed.
    WU's are being completed and processed correctly.
    The server seems pretty stable over the last 6 days.

    The old address cannot be forwarded to an A-name address and I cannot get a fixed IP address in a short period of time.

    So, for the foreseeable future the FDCPS project will be on http://fdcps.no-ip.org/

    You will need to change the hostname in your llr-clientconfig.txt file to "fdcps.no-ip.org" to get pairs from the ports.

    Please post here if you have any issues.

    The FDCPS server is running but a planned network change did not go to completely to plan yesterday so it is not available yet.
    The old DSL modem couldn't handle the higher rate any more and failed to hold sync.
    The new router is working fine but it won't update the dynamic DNS automatically.
    I should have the work-around completed today.
    But fast?
    The connection updgrade is completed and the connection speed is much higher (d/l 5x, u/l 1.2x) and the available usage ceiling is much higher too (4x)
    So well worth a few troubles of adding a DNS work-around.

    There was a local unplanned power outage this morning that lasted for about 5 hours.
    When the server came back up the clock was wrong and it performed the next roll-over before it was scheduled to.
    I fixed the clock and re-tagged the extra set of files so they won't get overwritten when tonight's roll over occurs on schedule.
    Happily the only person inconvenienced was me

    My pleasure.
    No really.
    I got 3 primes early on.
    None since then, but that's ok because they were good ones
    Great to see your post.

    Full DR plan execution and tests for FDCPS completed successfully at 2012-05-20.
    Because DR procedures are not 'good' unless you keep verifying that they work.

    The FDCPS server PSU fan bearings made some bad noise while at max RPMs during a heat spike about a week ago for a few hours, so it was time to check on a few things.
    I made a few updates to the rebuild document during the DR test, but there is one more item outstanding, so I'll commit that back into the project tomorrow.
    The project server runs well in a KVM cluster so I'm planning to migrate it to a KVM guest back on the same hardware soon-ish to get all the benefits that brings.
    I also verified that the implementation works with Nginx . (very snappy btw)
    I'll add that config to the doco for the commit tomorrow.

    It went so well I am still looking for the "Gotcha!"

    The FDCPS site and ports may be unavailable for a few minutes in 3 hours time [16:30pm AEST and 06:30 UTC] while I migrate it to another machine to allow the server maintenance and OS upgrade.

    FOUND IT!

    That went badly.
    The network bridge to the VM version of the server failed.
    The version to version upgrade of the OS on the server box failed because the server network configuration failed between 10.10 and 11.10 so it lost all network connectivity and failed to boot, meaning that the next OS version upgrade was a dead-stick.

    I am now doing a clean install on the server box: ubuntu-12.04-alternate-amd64

    Having tested the DR plans I have the tried and tested recovery path so it's just a matter of time.
    Once the OS is running I'll have to rebuild the databases, web and mail servers etc.
    Not confident of getting it all done tonight, but it's on the way.

    In spite of copious testing, sometimes things that can go wrong still do go wrong.

    Damn you to the infernal depths of hell, Murphy!

    FDCPS outage:
    ISP maintenance activity is scheduled affecting local, national and international access.
    It appears to have started several hours early so the window is now much longer.
    Expect problems accessing the server for the next 9-10 hours.

    planned outage is complete.
    it took a little bit longer to tidy up some config items.
    The server is a little bit quicker at everything now.

    FDCPS server is down due to an unplanned lightning strike which has upset more than just a few electrons.
    Tomorrow I'll migrate the services to another machine, then see if I can recover the hardware.
    ITMT - apologies for the outage.

    Unplanned outage of FDCPS project.
    The server is not out.
    The site is not out.
    The comms are not out.
    Microsoft has hijacked NO-IPs 23 free domains & DNS, with the permission of a US judge, to 'filter' out a few bad hosts and in (predictably) failing to do so appropriately has created a denial of service to pretty much everyone with a no-ip dynamic DNS.
    ETF - unknown. Somewhere around the same time as someone important gets the judge out of bed to revoke the order probably.
    Hosting a site from the southern hemisphere on an OS that has nothing to do with M$ does not keep you out of the M$ blast zone.
    I object that a US judge deems that they can sign off that M$ can highjack an international highway to identify and stop the defective 'vehicles' that they built and sold instead of demanding they issue a recall.
    This is no april fools day.

    The fail:
    "In the meantime, NO-IP / Vitalwerks have published their answer online:
    Apparently, the Microsoft infrastructure is not able to handle the billions of queries from our customers. Millions of innocent users are experiencing outages to their services because of Microsoft’s attempt to remediate hostnames associated with a few bad actors.”

    Hopefully normal service will resume shortly.
