   The splice is complete and the Arelion link is back at full light level. We are re-enabling it gradually and watching error counters.

   Arelion has confirmed a fibre cut caused by third-party roadworks about 9 km from the site. A splice crew has been dispatched. We are operating on the second carrier plus the exchange for the duration, with headroom for peak traffic.
