Yah, here's me thinking I was alone. Let put what I added to their service portal early this morning.... (after encountering the same head-banging as you)
> We have two external IP feeds, one via Telstra (AS1221) and one via Optus (AS7474), DC Two is AS132145. > Using BGP AS-path stacking, we balance the inbound feed between the two, and use a round-robin for > outbound path selection. > Something broke within either Optus or Telstra last night around 19:00 Perth time (that's +0800GMT), with > one of the providers "stealing" our BGP routes which stopped us seeing a large of the internet. If I turned > off the Telstra pipe, nothing changed. If I turned off the Optus pipe, everything came back. (well, mostly > everything) So I left it like that for overnight. > Now, I currently have "deny all" filters for both inbound and outbound in place on our BGP config for Optus. > The only place you can see a path to AS132145 is via AS1221 according to various Looking Glasses around the world. > The issue is that external clients with Optus connections (NBN, Mobile and Fixed data) can not connect to us, > they are NOT being sent via a path to Telstra, they are being blocked from accessing AS132145.

I'm hesitant to send this, as it's very imprecise, so I apologise to anyone who gets annoyed at someone obviously groping in the dark, but here goes... Is anyone seeing routing or traffic issues with Optus services today? I have an Optus service which appears to be only partially advertising my BPG somehow - resulting in very intermittent inbound traffic.The advertisements seem right, the BGP peering is up, the routes are advertised - the only hard indicator is that the Optus link is carrying much less traffic than is usual for this time of day. Traces inbound are showing paths via my secondary link which shouldn't be happening (BGP advertising is setup to direct the majority of traffic - except for the second link's peers - through the primary) from some locations overseas and through the Optus link Attempts to log a fault with Optus have resulted in much frustration and head banging on desk - however I have an anecdotal comment from one of the Optus people I have got some sense out that they have been hearing of a lot of issues with internet services today. Anyone seeing anything that might match this depressingly nebulous fault description? I know there's not a lot of information, but I don't have a lot more other than people can't connect to various IP's in my advertised block, and some traceroutes which are less than informative. Thanks to anyone who can shed any light.
