Someone would like us to try to configure a Juniper router for them to go on one of our lines.
I was inclined to say no anyway, but normally we would at least give it a try, even though we have never set these up, and he did not get it from us.
But this nagging feeling hit me - if we try - and we fail (quite likely as we have no experience of them) - we could be liable to ADR.
So I said no.
Maybe when this is all sorted I'll be less paranoid.
