Dear IS Customer

Wednesday, 2nd November 2005.

IS has, for quite some time and certainly longer than a year ago, maintained standard configuration to detect, and re-route excess traffic, on the peering circuit between IS and SAIX, via its international links, to maintain service, primarily in the face of outages of the peering link, but also more recently under extreme peering congestion. The solution works transparently. When the peering circuit is working within capacity (i.e. within the 140mb ATM limit imposed by Telkom which is insufficient) there is no re-routing that needs to occur. Currently, we routinely see excess traffic peaking at 50Mb/s.

Earlier this week, SAIX implemented filters that prohibit the entry of IS-based addresses via their international links. This, in effect, incapacitates IS configuration to effect automatic re-routing decisions, and has the overall side effect of denying IS access to the SAIX network, in the event of a local peering failure.

In the current situation of endemic over-congestion on the peering link, significant volumes of traffic would continuously flow to the SAIX network via IS' international bandwidth. IS is now dropping 70mb/s on the IS side of the interface to the peering link with SAIX. We have escalated this to an Executive level within Telkom to assist with the resolution of this issue.

This is receiving urgent attention and we will keep you informed of the status in resolving this problem.

BTW this has a huge affect on businesses running on both the SAIX and IS networks. This has been an ongoing thing from what I understand because SAIX refuse to share the costs to upgrade the link. Now in even further uncompetetive behavior they are blocking all exccess traffic.
 
Solution... switch to UUNET - that's the network MyADSL is on at the moment and they seem to have the least problems. I am sick and tired of this spat between IS and SAIX costing ME money and clients. I understand the reasons for the problem and I sympathize with IS to some extent, but the reality is that I have to work and this is just rubbish!
 
This is having an effect on businesses. We have not been able to send email from IS based servers to SAIX based servers during business hours since yesterday afternoon.
 
Telkom is CRAZY! What basis do they have to deny traffic coming into the country from their US peers? Whats gona happen if the peering links in SA go down? Usualy the backup would be via the US, now there would be none.

Never mind escalating it to higher Telkom management levels, government as a regulator and a major share holder should put their foot down and say enough is enough. Clearly Telkom is trying to milk everyone for as much money as they can and they will stoop as far as they can to cause the most inconvenience and disruption they can to force people into having to pay them more.

Telkom's stance on this peering issue is nothing short of totally wrong. We pay for bandwidth on our SAIX accounts and we expect to get it at good speeds. If we are pulling that bandwidth from another ISP, then we have paid Telkom money and we expect them to pay that ISP for the bandwidth so we can receive that content. Telkom do after all charge us for bytes RECEIVED and sent.
 
It's disgusting behaviour on Telkom's part but the reality is that almost all of the legislators who make the laws are incapable of explaining what the internet is let alone make an informed decision about a technical issue like this.
 
You forget that SAIX claimed that local badwidth costs them next to nothing... this is the reason why it costs them nothing (They simply refuse to spend money on it).
 
No wonder the international is so bad on IS ADSL.

The inadequate peering link between IS and SAIX is to blame here. Traffic that is supposed to be local peering is being sent via the USA and back to SA. This causes the knock-on effect that the international pipe is congested.

ICASA needs to show face and do something about local peering agreements. One local backbone provider like SAIX can not hold the whole country ransom.
 
Yet another example if Telkom's "economic terrorism" as it has so often been described of late...
 
Time to arrange a country wide protest?

Or could Debbie2 or rpm contact the new Telkom CEO and ask him to put a stop to this nonsense.

He should decree that Telkom immediatly doube the peering speed with IS for no further costs.
Then they should look at introducing a fair peering policy in general for all ISPs.
ICASA will do it for them soon if they don't anyhow, but we will all have to suffer till Feburary to wait for that.

IS, together with SAIX, have resolved the issue around filters that were prohibiting the entry of IS-based addresses via their international links, as communicated to you yesterday. This service has been restored.

Just got this
 
Still ridiculous that so much LOCAL traffic goes all the way overseas and back.

At ICASA 2 weeks>= 3 Months, therefore, February = ((4*4)/2)*3 = 24 Months

So we will have to suffer till November 2007. :)
 
I would also be cheesed if I make my own free Int link and is caught "wiff my pant” down, what you mean this is not Zim?
