OK barge-bridge collision and collapse
A few people asked the interstate-40 bridge collapse in Oklahoma across the Arkansas river. 11 and possible as many as 20 people are believed dead. Although I-40 is a major cross-country interstate, the bridge collapse had no apparent impact on cross-country telecommunications traffic. I'm not aware of any fiber routes across that bridge.

You are not the only one, We also have had many problems with them regarding this issue and were essentially stonewalled. Any of our users in the .co.za namespace are unable to use ns3 or ns4 of our nameservers. It's a shame especially because it seems to be such a worthless requirement.

They have a script that checks if YOUR nameserver knows about ITS ip address and they query for the 1:1 in.addr-arpa mapping. If your nameserver does not provide an answer they like, they are unable to let registration go through. Our nameservers reply with a SERVFAIL as they are not authoritative for their 1:1 in.addr-arpa mapping and only know about the RFC2317 indirected one. I argued about this with them *at length* and they kept inventing more reasons why I was breaking RFC compliance. They even told me they couldn't accept my nameservers as these would 'waste bandwidth' which was 'terriby expensive' in South Africa. It probably is, but that has nothing to do with my nameservers and their reverse delegation! In the end sanity more or less broke out and one of them stated that they were very busy with legislation &c and unable to change a script that was only causing problems for me and for nobody else. Now I doubt the last part, but I can understand them being undermanned. And then we gave it up. Good luck to them all.
