Media reports yesterday claimed that as many as 2 million+(althought the figure could well have been higher) BT customers saw their broadband service offline on Tuesday due to an Outage ? With BT being the number player in both telephone and broadband service within the UK why does there appear to be a wall of silence as to the reason and cause of this system failure ?:wave:

I think the kind of router they're talking about probably looks more like this: http://img.directindustry.com/images_di/photo-g/61398-3128347.jpg Rather than the little things we're used to.

Exactly, all it takes is one of these routers to start sending spurious messages and the whole system can grind to a halt. Everything has to be connected, so that's why it affected so many people. The problem would probably have been there for a while, but the nature of routing means that it would not have been spotted until it caused an outage.

But surely they should have had a clone that would be able to kick in once the first went down?

obviously wasn't thinking of it being a desktop server...honest

Love the corporate speak that always says 'some customers have experienced some temporary loss of service'. Sounds so much better than saying 'all our customers were f*cked because our system crashed because our techies were hustled by their managers into doing an overnight upgrade that hadnt been given adequate testing time'.

Agreed it will have been some datacentre level router but if 2m+ people can be affected by a single device failure then it's a very poorly designed network. Equally there are tools to monitor the health of the routing protocols and that can take self-healing actions to prevent this sort of outage.

A bit shoddy if they running all their broadband from a copper CISCO switch. Only thing those things are good for is demonstrating air flow on a data centre mock up.

They don't - BT's favoured vendor for core devices is Huawei.

Wow, one router looking after all those people with no automatic back up, or at least an alert for manual transition to back up - pretty poor, where does all the money we pay them go?

Premier League football teams, Michael Owen and Robbie Savage. :facepalm:

I don't think you can have a clone as such, but as [MENTION=1365]Westdene Seagull[/MENTION] says they should have had better monitoring in place to prevent it, and remove the router from the network. It could have been a "perfect storm" of issues which were hard to pick up.

Corporate speak,you mean like this ? When buying a airline ticket you are a customer,however should the plane crash and everyone is killed you revert to being a passenger. Well let,s face it,it,s rather bad for customer relations to slam a plane onto a mountain.

Did anyone lose service on here? I checked and we didn't lose any connection with BT on Tuesday - unlike the regular down times we used to get with Virginmedia

My BT Infinity FTTP in Billingshurst stayed up throughout, but all sorts of stuff was inaccessible through BTInternet, including my work VPN for a couple of hours, which was not nice. Fortunately my Vodafone 4G tether worked nicely as an alternative.
