Vumatel outage ?

GoB said:
There was no loadshedding for the 15 hours prior to the break this morning for myself and Slootvreter, so I'm making no assumptions regarding loadshedding until proven otherwise.

Probably a downstream issue,. the ONT had the LOS on, so there SHOULD be Internet, but there was not.

I am again sitting with no internet, our power came back on at 16:30 already, and it's now 19:00. How do you explain that Vumatel? Surely your network can't cope with power outages. Stellenberg Area, Northern Suburbs.

Their CPE boxes uses DHCP to connect to the network ... after loadshedding all these devices are flooding the network with requests and they can't handle it ... they DDOS themselves.

Yup, most of the complaints have been from Northern Suburbs, Cape Town. Vuma is keeping quiet, I don't buy this DHCP DOS story.
 
What pisses me of the most is the lack of communication from the ISP (looking at you WebAfrica) and a concrete plan of action what is going to happen to resolve the issue with timelines.

Why I am paying over R1000 to these ISP clowns for if all they do is bill me ... have a support line or more accurately a human ticket logger that closes at 8pm and send me a monthly invoice ???.
 
Just give us (with static IPs atleast) the damn config so we can manually set it.

You don't have to buy it lol, doesn't mean it's not true, have a look at you router's logs, 1billion DHCP requests to finally log "no offer, DHCP service unavailable"... Looks like DoS (self inflicted) vibes to me :( farking irritating at the very least, I have an office at my home, so far I've lost almost 6 hours of work time, looks like it will be 8 hours at least after this drama. Who is going to pay for an entire day of lost revenue??

Mine was back at 6pm - left the router alone. But I need to replace my backup battery to try and avoid this.
 
I'm annoyed by their patronizing SMS blaming the load shedding as the primary reason for all of this.

Normally, I'd say "vote with your wallet and move on", but for many of us Vumatel is the only infrastructure provider we have access to.

So, I'm thinking that the best way to protest is pick a day, and downgrade one or two plans lower on that same day to send them and their ISPs a clear message that we're not only unhappy with how this happened, but also the complete lack of honest communication that we've encountered during this problem. Do that along with some hashtag on twitter stating why it's done, and it will certainly get their attention.

Would anyone be interested in participating in that?
 
I am going to ask they sent me Rain data sim at their cost since my 50/50 fiber is useless atm.

One day is ok but it is approaching nearly 3 days now.
 
Almost 6hours after load shedding and still no fibre connection. Rumours running arround some Vumatel box burned down after load shedding.

As you are aware, Vumatel hosts the DHCP server internally on the Active Ethernet network. With the introduction of load-shedding on a mass scale, we have seen DHCP broadcast storms after the power has been restored. Whilst we have segregated the network into smaller DHCP domains, the volumes of DHCP requests, given the size of the load-shedding areas, are still considerably high.

These broadcast storms have resulted in some ISP customers (end-users) receiving an updated IP address, in some instances, later than usual. In a worst-case scenario, this has been recorded up to 2 hours after the power has been restored. The sudden volume of DHCP requests results in some DHCP requests being dropped by the Vumatel switches, requiring repeated DHCP requests before the ISP modem receives a response and assigned IP address.

have you switched it off and on again ..lol

but seriously, how many requests are there if you enable the subscribers fiber a few at a time. or is is this what was done or was it just left to sort itself out eventually.

some people seemed to be offline for a long time.

So, clients must wait two hours after every outage, surely they aren't serious ?

Our Vuma based fibre was working as soon as load shedding ended.


You guys cant seriously blame Vuma for this, of course the DHCP server is going to get f**ked by all the requests.


Buuuut they should have it so that each region ie CT, Durban and Gauteng have different IP ranges to reduce the load.

im actually more inclined to believe it has to do with their device mac address registration requirement

Which ranges each region use has nothing to do with dhcp load. Also, dhcp is really easy to scale and to segment so it's incredibly likely to have been at the core of this outage, it's just the sympton you see on your end.
 
I posted this in CISP thread, so far this is the only reasonable answer to the woes in Stellenberg/Brackenfell bordering POPs

Right, many do get back online after loadshedding but depends on your area per my previous reply relating to the specific issues we experience in Stellenberg/Brackenfell border.

Are you in the same area, I am guessing no since you are online. Everyone in this area experiencing the exact same issue that fit perfectly with the POP melting down essentially however vumatel is not expressing the issue to anyone.
 
I put my stuff on inverter yesterday. Left just after loadshedding started and got back 20:30 last night.
Everything was still working fine.
Suddenly at approx. 10pm internet just went down mid browse.
Quick question. If I have trenched Vumatel, I'm fukked correct? No way to get onto another backbone?
Can anyone recommend a WISP for Brackenfell North, close to Bottelary?

You must really be desperate as my experience with WISP's has been slower than a USR Robotics Sportster 2400 baud modem.

Why don't you use cellular in the mean time ???.
