Planned Maintenance: Telford-dc3-2.core

Posted: April 23rd, 2018 at 17:41 by Gurinder Bansal

Wednesday 2nd May 2018 00:01 – 06:00

During the above window we will be replacing telford-dc3-2.core.enta.net with a higher capacity router.

All services currently terminated in this location will be migrated on to the new hardware. This includes leased-lines, colocation and pseudowires terminating at this location. Whilst actual downtime is expected to be no more than 30 minutes for each circuit, the full 6 hrs may be required to account for any unforeseen issues.

All other traffic that would normally route through this location will take alternative paths.

Planned Maintenance: Telford DC2 Equipment

Posted: April 17th, 2018 at 21:11 by Jake Turner

Tuesday 24th April 00:00 – 06:00

During the above window we will be relocating the below equipment out of DC2 in Telford and into DC3. Downtime for each device should be no more than 30 minutes at any point within the window:

  • pwan-diag
  • pwan-kikker.edge
  • pwan-tlf.edge

Please note that during this window the Mirada virtual machine used for troubleshooting will be unavailable briefly and whilst pawn-kikker.edge is relocated all PWAN devices will show as unreachable. This will however not affect the operation of PWAN devices and no downtime will be experienced as a result. During the move of pwan-tlf.edge some customers will experience a loss of connectivity to colocation in Telford from their PWAN. Individual customers will be notified separately if this will directly affect them.

    Apologies for the inconvenience.

  2. Jamie Smith says:

    Further to the most recent update;

    VM have come back to advise that this has now been escalated as a fault due to potential faulty fibre patches and possible faulty amp related to medium power work.

    VM have despatched engineers to site to Investigate the issue further and work towards a resolve.

    I apologise for any confusion as the previous update had been incorrectly advised by the supplier.

    Updates will follow in due course

  3. Jamie Smith says:

    The affected core link is operational again however we have yet to receive an RFO from our supplier. As such should still be considered at risk until further notice

Incident:Vodafone Circuits

Posted: March 23rd, 2018 at 14:50 by Jamie Smith

We have experienced a brief loss of service to a number of Vodafone circuits  Initial diagnostics indicate the circuits are related to a single Vodafone handoff. Engineers are investigating and engaging with our supplier.

The circuits in question are now showing as back up, further updates to be provided.

  1. Scott Morgan says:

    After further discussion with Vodafone, they have confirmed the brief drop of connection was caused by human error.

    Whilst conducting diagnostics on a leased line fault, a Vodafone engineer inadvertently carried out loop testing to a Vodafone hub serving Entanet customers. As a result, this caused disruption between 14:43:45 until service was restored at 14:48:09 as the engineer rectified their mistake.

    We apologise for the inconvenience caused by this. We are in talks with our suppliers to see how this can be avoided in future.
