    The cause was a fire in Parkwest or Citywest apparently . Only the legendary beecher.net in Cork survived the carnage .

    From what I could see it only affected sites hosted on hosting365. We have dedicated servers there and we lost them for just over 30 minutes. Site hosted elsewhere appeared to be unaffected.

    Beecher.net is hosted in the states, so it would not have been affected.

    I was able to get onto sites hosted by blacknight, and the RTE Site was grand too.

    What happened to the Hosting365 redundant tier 1 connections...

    It looks like they turned off the power to the whole building.

    I guess that's the end of the 100% power SLA then.

    To be fair, an SLA isn't an uptime guarantee, it's an agreement that if downtime is experienced, the customer will be compensated. 100% uptime just doesn't happen without massive investment -- multiple machines, multiple ups', multiple generators, multiple geographic locations, etc, etc.

    I'd be curious why the redundancy systems (appear to have) failed in this case though, it seems odd.

    I would attest that to ftp.heanet.ie being offline for quite a bit of the day as it is being moved to its new home in servecentric :)

    I got a ticket about server moves for a totally unreleated reason, didn't put 2 and 2 together. :)

    Our network wouldn't be affected by an ESB power outage

    Update from H365 here. A bit late in coming and the outage really should haven't happened in the first place, but sometimes the gods work against you. No doubt the lads in 365 will learn from it.

    Things like making sure your dual PSU servers are fed from seperate PDUs which in turn are fed from seperate rings/phases.

    Sounds blindingly obvious but you'd be suprised how easy it is to forget which PDU is which when racking a server. :(

    I suspect most techies will look at this as a case of "There but for the grace of God go I" and promptly check their own cabling very discreetly.

    Backups are the same. As soon as everything is back up and running, you walk away to catch your breath. Then a few days later you think to yourself: Arse, did I ever restart the backup processes? So easy to do.

    Just goes to show that a little knowledge can be a dangerous thing.

    You should be looking for the same phase from different supplys. If you have a dual PSU server connected to two different phases EG L1 and L3 you would have up to a 400V potential difference between live on both of the PSU’s. All you need is to loose the netural on one of the phases and BANG there goes your server. You will also loose neutral easier that you think, lets assume you are removing ome of the supply leads and rock it from left to right when removing there is a 50% change the neutral will disconnect before the live.

    Yes you are right, and thank you for proving it. :rolleyes:

    EDIT I was going to leave it at this but seeing as I'm feeling peeved

    http://www.cisco.com/en/US/products/hw/switches/ps708/products_installation_guide_chapter09186a008020e0d3.html#wp1026596
    All AC power supply inputs are fully isolated.
    -Source AC can be out of phase between multiple power supplies in the
    same chassis, which means that PS1 can be operating from phase A and
    PS2 can be operating from phase B.
    -Source AC can be out of phase between AC inputs on power supplies
    that are equipped with multiple AC inputs, which means that power cord
    1 can be plugged into phase A and power cord 2 can be plugged into
    phase B.

    HP, Dell etc all do the same and isolate their supply inputs. I can dig out the technical docs for you if you want :eek:

    Try googling switch mode power supplies, subtle difference from transformer based power supplies. It'll get you pointed in the right direction, you might even figure out why they are isolated.

    I'd be more worried that it took 27 minutes to find the circuit breaker, let alone the clearly flawed planning of the electrical systems!

    Which means you have considered using IMPROPER Data Centres at some stage :D

    You better hope Blacknight NEVER has a power outage because that comment there will come back to haunt you ....I assure you :p

    Um. Is this from experience, or hypothetical? How, exactly, does 400V potential difference between the live feeds (to two completely separate power supplies) translate to BANG?
