Cool Ideas Fibre ISP - Feedback

During loadshedding when a suburb gets power again vumatel experiences what is called a DHCP storm on their trenched networks.

It can sometimes take an hour or more to resolve.

Again, not something we can control or fix.

If it was PPPoE on our own infrastructure we could auth thousands of users within a few minutes.

Yeah... Makes sense. The other times were only stage 1 or 2 loadshedding, so can only imagine how many cpes are yrying to connect

It looks like there was a carrier issue from Cape Town to London, but it has been resolved. Apologies for the interruption.

Hi also durbanville and no internet since loadshedding ended. Could the chip in the cpe box have broken? Tried connecting directly and got nothing.

Edit: back up guess vumatel had some issues heh

I dont think any CPE issue except that for some reason the vumatel area substation where we connect to is either dead or not getting any IP assignment from the main network.

This is why I am keeping this discussion going. Never before have the network taken longer than 30minutes to come back on after loadshedding, it is now approaching 3hours.

On 6 December, there was a similar outage of about 2 hours. Worst part is you can't do anything.

 

[Orihalcon]

Throwing my hat in here. Vumatel trenched in Brackenfell. CPE synced...no internet.

 

[Bighit]

And it's back up in Durbanville. 3 hours after load shedding. Not cool Vumatel

 

[Hunted]

I'm back online in Uitzicht Nothersubs CPT again, however teamspeak keep dropping which is hosted in JHB.

Speedtest also showed fine Getting the 100/100 to Randburg

 

[Tinuva]

I am looking at getting a battery solution at home to connect to the CPE and modem. Does Vumatel Fibre stay up during loadshedding or will I just be wasting my time?

Mine stays up with inverter right through loadshedding. On vumatel and cisp in bellville.

 

[John Tempus]

How is that possible? If the vumatel distribution unit you connect to have power failure then no amount of inverters at home will keep the network up.

This is exactly why home off grid power is pointless if the main issue is having internet access since internet access is dead external from your power source.

Thanks for this @TheRoDent.

As someone said we'll be down until the next rolling blackout when the cycle will begin again. Not to mention the JHB storms when we have to unplug our routers :crylaugh:

 

[Orihalcon]

Glad to read that people are coming online slowly. Hopefully soon in my area.

I'm going to guess that we connect to a different vuma board than bellville does

The distribution point that you connect to would fall under the same power utility area. For instance vumatel wont route your closes distribution point outside the same zone so if your power in your zone goes down the distribution point would also go down.

Most if not all distribution points is within 1-2km radius from where you stay.

 

[Bighit]

Then it doesn't make sense why @Tinuva would be unaffected.

 

[PBCool]

Then it doesn't make sense why @Tinuva would be unaffected.

DHCP storm if the IP stays allocated in theory might not be affected.

 

[Hunted]

@PBCool , Whilst playing on PUBG I have micro disconnections to the EU servers, could that be due to the issue you had with your link to the UK or still due to the influx op IPs and traffic that gets generated with new users joining the network again.

 

[ArtyLoop]

the whole country is struggling, ESKOM stage 4 load-shedding, alles op gefok, mobile, internet exchanges, ISP's Fibre networks .........

And ZUMA is laughing his ass off at us
