No this was longer than 3 minutes ago. Everything is working for me again. So what was the problem and what steps have been put in place to stop it happening again?

whoa .... backup a bit, you do understand how big and complicated IP networks are don't you ? , when you run large networks there is a huge anount of change control procedures and equipment involved, it also has experts at various levels that will run through any outage, analyse and work out what went wrong, if anything is in error then procedures will be put in place.... sitting there demanding an answer on what broke and what is put in place is pretty bolshy they only just brought it back online... they won't have an answer untill the experts understand the issue and breakage.

There is, but you still get routed through the load balancer/switch before the web cache before it bypasses the web cache.

I'm on the bypass and was impacted by the outage as well. It seems as though they're completely bypassing that infrastructure which is an interesting fix..

The cache has had so many problems it's likely costing more in time than it's saving.

Indeed, I'm just hoping this incident was the final nail in the coffin for that solution

@defnz: if you are in the bypass correctly you never touch the load balancer.
@Ragnor: This can be said of many many implementations of ISP level HTTP caches, I ve not seen one yet that didn't require a constant eye, its why so many are scrapped and then rebuilt once the old lessons are forgotten.

My views are my own, yada yada.

I did request my IP be added whilst you were still there so am just basing it off observations I've made with tracetcp

OK.
Then you should be bouncing through the router at the front door of that cache farm then...
Not touching the actual layer4 devices.

A complete bypass is just the quickest way to restore service, hunting the wumpus in that thing can be a real challenge.
