    RFO Friday 11th July

    10:13 A  router card failure was identified at one of our Datacentres in Enfield. Although the router failure was only for 10 minutes and returned to service at 10:23, it caused an issue with the routing of calls whereby either the call was terminated or it made the call became unanswerable.  
    10:50  After identifying the cause of the failure, the affected card was removed from service and the BLFs were disabled, to allow the routing to stabilise.
    11.42 The fault was resolved, with services being fully restored, apart from BLFs, due to the load that would suddenly be added to the servers

    Weekend of 12.07.25 to 13.07.25 - BLFs were switched back on and all services to the network made fully active

    To prevent this incident from reoccurring, the affected router will be replaced on the weekend starting 19.07.25
