In networking, it's more than just flipping a redundancy switch as mentioned.

Obviously, everyone wants that, and any problems would disappear in the next second.

 

Unfortunately, a lot of diagnostic troubleshooting and technical knowledge is required, if the redundancy switch does not solved the problem.

 

From the server (DHCP, in this case) to the client (subscriber's unit), there's usually a whole bunch of switchers, routers, and routing protocols, in-between that need to be troubleshoot.

 

More to the point, is there anyone here willing to pay 2x the price to have this "redundancy" system? Effectively, what you are asking for is 2x the infrastructure and 1 set will just be sitting around doing nothing 99% (or whatever the normal uptime is) of the time?

I think i set up one in my HDB. Then run the "redundancy" in the corridor lah.

 

So freaking easy.

 

 

 

zzzzz. lousy business model.

 

Haven't start up already got low cost competitor in hdb

Actually, a redundant server is not really expensive. It's just another machine + software that you paid for.

 

The problem is the network can't be easily made redundant.

You can create loops if not careful.

 

The network topology changes even when one of the ports of a router is dead.

They need a dynamic routing protocol to prevent such loops from happening.

 

It's like a road traffic network. When a lorry tipped over and block all the lanes of an expressway, there must be a system to divert traffic to other roads, or else everything comes to a standstill and the traffic keeps piling up from behind and the usual kpkb.

 

Again, that's where you need competent (network) engineers.

Is what we are looking at just 1 redundancy server? Or redundancy in every part of the system? There are other things that can go down other than the DHCP server - then people will be asking where is the redundancy for that.

This outage should be on next COE bidding Final Day from 3PM onwards till latee at night !!!

 

At LTA Server...

 

Agree...

 

They will just void the results and hold it again the next week la...

the entire spore engineers, all telco bandwidth reroute, data scientists, all kaypoh person will be channeled to LTA

it's unbreakable ... LOL

You've already indicated that it is possible.  

The limiting factor is usually cost which translate to whether it makes business sense.

 

An additional piece of hardware need not necessarily be redundant. 

It can be configured for load balancing which maybe translate to better service.

More to the point, is there anyone here willing to pay 2x the price to have this "redundancy" system? Effectively, what you are asking for is 2x the infrastructure and 1 set will just be sitting around doing nothing 99% (or whatever the normal uptime is) of the time?

 

Some redundant hardware can be set for load balancing. 

Sounds easy.

 

Tomorrow I go set up an ISP.

 

Competition is good.

It depends on telco network design.

Generally it's huge and servers are divided into clusters.

 

Example, say for west side, all Jurong, bukit panjang, choa chu kang, etc can be assigned to a redundant pair of DHCP servers, and the east side another redundant pair of DHCP servers and the central and north yet another pair.

 

Then there's the server location. Where are they ? Are they centralized in one area or decentralized to the location where there are serving ?

 

Every server is then inter-connected in a vast networked system.

 

If a particular DHCP server got a problem, redundant server can takeover or worse case affects only one particular hub or cluster.

If the network develops a problem, then all the redundant servers are affected, no matter how many you have.

 

Added to this complexities of servers, there are also other servers like DNS that telco is operating.

Trust me, cost is the last thing that local telcos are concerned with.

Yes, they may baulk at brand A vs brand B server cost, but they are NOT going to go without redundancy or that server.

 

In other 3rd world countries, cost is often the single most important thing, and they will do without redundancy.

But then, the local population is used to lower standards and usually lower subscription price.

Maybe its time to give all subscribers some Christmas present, say free data usage during the long 3 days of Christmas holiday ...

 

Something like all Singtel MIO & broadband subscribers will receive iPhone 7 Plus each as Christmas present .... :a-happy:

 

 

Wait long long .... :XD:

Telco = business = profit driven entity  [laugh] 

Cost is forever an issue, if not don't need to outsource.

Singtel disruption: Fibre broadband services fully restored, 10% discount on broadband subscription for December

 

http://www.straitstimes.com/singapore/singtel-disruption-fibre-broadband-services-fully-restored-10-discount-on-broadband

 

 

Got discount meh? 2/31 out of service. More like proration of subscription in disguise. Use the discount word to fool people into thinking they got a good deal when in fact merely to not charge for services not rendered.

Still no access for some Singtel subscribers

 

 

Some subscribers of Singtel broadband were still without Internet access yesterday, a day after the telco said all its services were fully restored on Sunday morning following an islandwide outage.

 

They were unable to restart their modems and routers to re-sync their connection to the servers despite following the instructions they received from the telco.

You don't understand. Our contract with them has no SLA so they could have still charged us the full price.

 

That's why 10% off is a discount.
