INFORMATION
  • INITIAL
    1½ years ago by Andrew

    Our monitoring has picked up a large number of BT circuits disconnected at 13:43. We're investigating

  • UPDATE
    1½ years ago by Andrew

    Most lines are in the process of reconnecting. Cause still being investigated.

  • UPDATE
    1½ years ago by Andrew

    We've lost all traffic on two out of four of our links to BT - oddly, two links are in separate datacentres. These are resilient links, so traffic will reconnect/move on to the remaining links. UPDATE: this does make sense as this 'pair' of hostlinks would terminate at the same point at BT's end even though they are at different datacentrres at our side. Our working pair of hostlinks would then terminate at a second location at BTs end. We'll clarify this when discussing this with BT.

  • UPDATE
    1½ years ago by Andrew

    Issue raised with BT. Our customers who were affected have reconnected.

  • UPDATE
    1½ years ago by Andrew

    BT have identified a potential fibre issue between Stepney Green and Upton Park, they have engineers tasked to investigate. This is affecting other service providers. As these 'Hostlinks' are dual/resilient connections, customers still have service.

  • UPDATE
    1½ years ago by Andrew

    The two links are back in service and traffic levels on them are back to normal.

  • RESOLUTION
    1½ years ago by Andrew

    BT say: Fault proved to a fibre bend at Mile End TE by PTO. Cleared at 17:25.
