And the fibre splicing is done. Customer traffic is flowing across the York to London link once again; the data centre is back to full resilience.

I spoke too soon - one of the cores needs resplicing. Finger's crossed we shouldn't overrun by too much.

Splicing at YO26 done. Now to test the new pairs.
Looking at the clock, we should be on time to finish at (or before) 06:00.

The main resplicing of circuits is complete at the newly-repaired joint. Now there's a little more splicing to complete within the data centre, to ensure that all pairs are connected and available for future use.

Apologies for resolving this early - we have a strange default when posting the first update(!)
The majority of the joint work is now completed, and re-splicing of the individual fibre cores is now underway.

Level 3 will be beginning the fibre work in about 40 minutes, so we'll begin moving our traffic away from the link between York and London in the next 10-15 minutes.

On Thursday the 3rd of December, beginning 01:00 (UTC+0) and finishing before 06:00, Level 3 will be undertaking works to rebuild a fibre joint that serves our data centre in York. This requires that both of our disparate Level 3 services will be offline during this work.
We are not expecting an interruption to any of our other network paths, so this notice should be treated as an 'at-risk' period only. However, the data centre will be operating with reduced resilience whilst the Level 3 work is ongoing.
Some customers may notice that their traffic from York to London peering exchanges will go via Manchester, most notably towards BT, Sky & Plusnet. This should only add around 2ms to the RTT.
I will be on site during the work overnight, so will provide timely updates to the case throughout the window.
