[nznog] TCL -> Callplus/Slingshot issues

All day yesterday I was unable to see any of the Callplus/Slingshot network from my TCL cable connection (obviously due to the Telecom problems). This issue was resolved last night but is now occuring again. I've given up trying to ring the TCL helpdesk (wait times listed as 90 mins despite no known network issues) so am at least hoping somebody reading this may be able to look into the issue if they're not already. All other internet sites from TCL are working fine so it appears to be some sort of routing issue somewhere..
