[AusNOG] SPAM-MED: Re: Vocus international service outage

Wed Aug 27 10:21:46 EST 2014

We don’t use Vocus as a primary source of bandwidth, but even so, we like to keep it live and attract some traffic to ensure it’s always available. Accordingly, we experienced the same problem.

Despite as-path-prepending a number of routes, this still didn’t work because of aggressive traffic engineering by major providers like he.net. Our only option was to withdraw the routes ourselves.

I’m not overly concerned that there was a problem – shit happens, but when it does, routes should be withdrawn if you can’t handle the traffic they attract.

Perhaps Vocus could consider a BGP community that would allow us to “subscribe” to having the withdrawal routes when a fault condition or maintenance is performed to ensure that there’s little/no risk of interruption when something like this happens?

Kind Regards,
Jonathan

We are also multihomed, and the only fix was to turn off Vocus.

Not sure if this is an option, but perhaps an addon feature for customers who are multihomed to have their service turned off incase of a degradation like this.
I'm trying to think how you would automate something like that...

It wasn't as simple as having transit through a single upstream being the problem.  While the vocus outage was happening, they were still supplying a full routing table. So those of us with multiple upstreams had to completely shut down Vocus to stop the outage.  And the whole situation wasn't helped by Equinix using Vocus for their outbound internationally, so a ticket had to be lodged there to have them turn off Vocus (which thankfully they did immediately)

Yup.. move along, nothing to see here.

Once an outage is fixed, those who dwell on the cause that they can do nothing about, are focusing in the wrong place.

If your only transit was through a single upstream, that is where you should be focusing, not the provider.

Hi James,

Still waiting for the RfO on this whole thing with the details. Neither seen one here nor as a follow-up to customer notifications.

Cheers,

Hi James,

Hmm - can understand that but would have expected that there is sufficient redundancy in the LA landing of your network. I would have expected that a re-route and taking SJC largely out of the equation would be possible. Surprised to say the least …

Cheers,
Wolfgang

Early mail is a power surge in a US DC has damaged both core routers. Wouldn't surprise me if transport from other providers out of that building will be having similar issues.

Circuits are being moved directly to borders as we speak.

Engineers are currently awaiting remote support in the US. Links will be physically moved from the failed device in order to restore services on an alternate device.

[hijacking the thread…]

They say there is a big rewrite coming on the way rpd and sampled interact in 14.2; and the slow convergance issues have been fixed in more releases than I care to remember right now… but people say they are pretty good in the 12.3r6 train. Our MX80's are slated for upgrade to that at some stage in the next few months.

Some noise about this on j-nsp again today.

True, but they otherwise work exceptionally well.

I’m not sure what kind of PowerPC CPU is doing all the work on an MX80’s RE, but I do sometimes wonder if the CPU on a <$40 Raspberry Pi might be more up to the job :-P

We've done the same (about 20 minutes ago).

Right now I hate how long Juniper MX's take to stabilise their routing table with sampling on.

Yeah we are seeing this! Everything running via them is flapping, they claim to have 'routed around it' but that's not the case. Very frustrating as it's been an hour and no one there seems to know whats going on....

Hey All,

Just saw the dashboards light up with connectivity issues internationally for Vocus services and thought I'd make others aware.

Vocus outage report is saying: "core network link between 59 Doody Street, Alexandria and 55 South Market Street, San Jose has failed" which hopefully isn't a Southern Cross fault!

Anyone else seeing this or have more info?

Cheers,
Andrew
