Looks like "ranger" was able to get things working well again. Telkom is a pleasure to use when all is working properly. Thanks "ranger"
There were more problems than we had expected due to the rate of DSLAM migrations over the past few months (meaning 10000s IPs moved to other regions), combined with some of the work we did in early December. The combination resulted in:
- Some subscribers exiting IPC in the wrong region
- Some subscribers exiting IPC in one region but going via a different region for international/transit
(Some of these problems are only because we have the most IPC capacity thus connected to more IPC routers on the ADSL side which makes routing policy quite complex in order to get load balancing right)
This obviously means problems with user experience and capacity planning being challenging.
We believe we have fixed the problems abive permanently, but will still be doing final audits (well, finalise some scripts to automate) checking all routes, and will need to tweak load balancing a bit more.
It looks like he cleanups have fixed most experience problems in Cape Town though because users in Gauteng are not using transit capacity intended for Cape Town).
Btw., we also updated reverse DNS (as evidenced by some of the recent traceroutes in the thread) so users can easily see which region they are in (but these records need to be updated, so can be out of date for a business day or two in the csse of newly (re-) deployed IP ranges) and which IPC region they break out from.
