If a jobs worth doing it's worth doing well, I know you said you don't want to go into the whole hosting issue, you get what you pay for.

I pay ÃƒÆ’Ã†â€™ÃƒÂ¢Ã¢â€šÂ¬Ã…Â¡ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€šÃ‚Â£24.99 a month for the service, this is at least 5x more than pro hosting costs so I expect a decent uptime, even if it isnt built for hosting on.

I suppose I shouldnt complain. Im just lucky Im not one of the poor souls on 10Mbps that don't even get anywhere near 2Mbps. Fact is I wasnt talking about my hosting or my server, thats the reason I said not to go down that road. Im talking about power outages and if NTL equipment has redundancy. Nothing more.

You shouldnt have mentioned the server

,
if i was still NTL i would be interested to know if i could still use the internet in the event of a power cut, as i have a power inverter i could use to power the pc from the car.

My area certainly doesn't have any power backup for the CATV/Broadband. There have been faults in the area with loss of service when the powere supply somewhere along the network has died. That's not necesarily to the local street (my house lights stayed on), but somewhere maybe even in the next town through which my services get routed.

Simple really there is no SLA on residential services so no obligation on uptime. If you need guarantees you have to pay more for professional suppliers (and that's not Clara.net - see my other thread

)

24.99 may sound a lot but if you want to put into perspective businesses can often pay triple that for a contended service with similiar speeds and why do they pay more?

They will get some form of SLA and possible better contention also usually priority support, you get what you pay for.

If you had a server in a good datacentre the difference would usually be there is some type of power redundancy even diesel generators in the event of a total blackout in the area, if the upstream is multihomed then you have redundancy on the transit.

If you was paying for a leased line and it went down at say 3am saturday morning you could probably expect it to be fixed very fast "whatever it takes" attitude from isp. A consumer connection would be more "best effort" and would quite possibly be looked at on the monday morning.

Its a bad attitude from an ISP but I understand your point. If only everyone could have SDSL at a cheap price...

So we have come to an agreement that the box probably doesnt have redundancy? I guess my UPS is just there to gracefully shutdown my server until the power returns then

As I said a few post ago, if a net tech is close by he will probably put a generator on it, but it will be down from the time the power cut starts, till he gets to the node, which is better than nothing.

A local powercut would have a 3/1 chance of being on the same phase as them, thats why you sometimes see only a section of an area go down.

So your backup is usefull

AbyssUnderground · 06-04-2006, 21:26

3/1? Dont you mean 1/3?

It is useful. I have 3 UPS's in my house. Two on my desktop PC (one for the pc and one for the monitor. Needs to be like this because if its running on battery and you turn the monitor on, POOF! PC resets due to the surge

) The other UPS is on my server.

300VA - server - 15-20 mins
650VA - desktop - 20-30 mins
500VA - monitor - 20-30 mins

Ive got a 12v battery and inverter if I need it to provide another hour of power for the server or pc.

Millay · 06-04-2006, 21:36

Looks to me like you got your UPS's round the rong way but each to his own, and why on earht would you want to switch on the monitor in a power outage?

Does the UPS not gracefully shut these machines down?

Nedkelly · 06-04-2006, 22:06

In this aera all Fibre cabs have battery back up .But if there is a power outage We can power up the kit in the street with generators or use the invertors in our vans .

Of course they could add a SLA to the residental services but then you would be paying more and probably be moaning about that.

The consumer market is sensitive to price changes and most people probably would prefer lower prices without the SLA.

How did I get them the wrong way round? Why wouldnt you want to switch in on in a power outage? The whole point of a UPS is so you can continue working and/or shutdown gracefully.

They only shut down when the battery power gets low. It minimises downtime.

NTL's uptime is excellent, Id say around 99%. My server has an uptime of 98.5% over the last 9 months. That is brilliant for an NTL connection.

Millay · 06-04-2006, 22:50

Well I would have thought keeping the server online for longer is your no 1 priority so, if you had not purchased a monitor ups you could have invessted in a 1000va + ups for the server and stuck a tiny one on the pc to shut it down gracfully.

UPS is not really meant for working normally during a power outage it is to allow you to save work and shut down. on a server you need a longer time so as to avoid disruption to your users. ie giving them a decent warning etc.

If you want to keep working through anything more than abrownout etc then you need a ups/generator mix...
