They should
They should and TBH you shouldn't have to ask, but you will have too. RIM have a contract with the telco's - they have to to run there services and for that they need link to the Telco's infrastructure via VPN link from there RIM servers to the telco network. Now if your a business customer you have your own VPN link to your own server. Business customers are ok, unless you one of the many sole traders or one of those people in the RIM advert who runs a business that dosn't use there own server. You are on what is for all effect is known as punter contracts and running a buiness on it. Now business contracts you have some protection from this as in compensation, same with BT home and buiness broadband, home is cheaper on many level, you now know why.
Anyhow back to compensation RIM's contacts have a uptime for there service in the form of a SLA and as all maintenance is ITIL'd out the ass as it's telco's were dealing with hear and they tend to take IT more seriously than any doctor takes somebody sneezing (Telco's are in permenant swine flu panic mode). So given this outage will most surely bust the SLA levels set on all there contracts for this month then you local telco (Orange in your case) will be paying RIM nothing this month for the service; You on the other hand will be charged as contactualy Orange can do that. Now fair's fair and if you contact Orange and complain you wil eventualy get a good-will gesture - Telco speak for ok were giving you some compensation for a mistake we made towards you but won't formaly acknowledge that as were so paranoid about admiting faults to our customers were it effects income we tend to keep as silent as possible. this is why you will have to chase Orange for compensation and Orange wont have to chase RIM for compensation.
So in effect it's on of those situations were RIM play real fair with there customers and there customers (IE the telco's who resell the service) are not as fair and actualy make more profit out of such events than they do when it's running 100% uptime with no issues. They also get to pass the buck onto RIM for there mistake they have admited to and are gladly playing fair and cool with teclo's who in turn get to shaft the customers by actualy making profit out of such issue's. Think of Telco's as banks in 5-10 years time and you can see how there going to evolve business and mentality wise.
So is it RIM's fault - if your a telco then yes, if your a customer of a telco who pays the telco for that service then contractualy your beef is with the telco and not RIM as you pay the telco your money and not RIM so you contract and indeed your only dealing are with the telco's. It is the telco who is the only player here that has a beef with RIM, RIM just been more open than other outsourced 3rd party services being resold.
So please BB all your friends when you can and get your telco's to pass on the good faith/good-will gestures on to you the effected.
That all said as RIM have been public, a little bit more official detail would be nice as saying a server died is like saying a computer died exactly and it's also like saying that there is a single point of failure with no redundancy and no DR which is something I, even of RIM refuse to believe unless they realy did get rid of all the wrong people managment wise. Which after this internaly heads should role, just that I suspect it will be the wrong heads again.
