Hi Tim,

With all due respect that is the update from 11 hours ago!

Our service has been down for over 36 hours at this point, and Lumen's response is "we will fix it at some point in the future, but not now"?!?

That really is unacceptable from a customer point of view.  We need the service we are paying for to be operational.  At very least I would expect detail of what the plan is to get it to that state.

thanks,

Cathal.

2026-08-25 20:22:05 GMT - The maintenance window starts at 12am CST. We will follow up again with the TNOC once the maintenance window starts.

Hi,

Please note the issue has not resolved for us.  The interface has flapped down over 2,000 times since 05:56 UTC this morning and remains very unstable, though it has improved slightly since ~07:45 UTC.  Please see attached file lumen_link_flaps_26.08.2026.png

Can you provide an update when available?

thanks,

Cathal.
