Thanks for the continued investigation and troubleshooting on this Chris - I'm sure everyone here appreciates it. Getting Telkom to respond was always going to be the tough part. MyBB is constantly trawling for news stories - I wonder if some publicity regarding the issue and Telkom's unwillingness to acknowledge it / help would speed up their response?
As a matter of interest - how does the temporary fix work? Routing around the congested hop?
There's no need to point blame, this was a very unique scenario and easily something that could be missed without the testing that we did last night.
There was a moment where the testing instantly had an adverse outcome and we stopped everything, narrowed it down, did a few things, found the issue, disabled it, and resolved the issue immediately. This identified the exact problem.
Our temp fix, is doing the same action that we did to find the problem. Our senior network engineers will be handling this until the perm fix is in.
