Telkom Mobile has blocked Sanral.
Can access it via Vodacom, CellC and MTN but not on Telkom Mobile.
No, Telkom Mobile has *not* blocked SANRAL.
Telkom Internet ADSL users can't access the SANRAL website either.
On one of our routers, if I use an IP from our ADSL range (105.22x.*.*) I can't access them, but if I try and access them using the IP on our transit link (thus, not our IP), I can access them. A traceroute from our ADSL IP range ends after it hits the Vodacom router. This proves that the problem is either at Vodacom or ETC (who hosts the SANRAL website).
We also tested on an Afrihost ADSL account (receiving a 105.237.*.* IP), and also couldn't access the SANRAL website from that connection (other users who received IP addresses on a different Afrihost IP address range could however access the SANRAL website). Additionally, from a number of overseas servers, I was unable to access their website.
Since Thursday, we have done everything we can in order to try and contact SANRAL and ETC in order to assist them in resolving the issue, trying to contact their network administrators via their published technical contact addresses (no response), emailing their general contact address on their website (3 days later I now have an 'account query' logged baseed on this email that states "Please find correspondence attached regarding your e-toll account"), calling SANRAL (their IT Dept said they can't help at all, they can't contact anyone responsible, they couldn't provide any other contact details), and calling the e-Tolls call centre (who said they had logged a call to their service desk but had no ETTR). I also logged a fault to our transit provider, who logged a fault with Vodacom, who established that the problem is definitely on the ETC side, but they could not provide any contacts at ETC.
So, no, this is not Telkom blocking anyone, it looks like ETC has a routing problem, and no-one is there to solve it.
In the meantime, as a workaround, Telkom Internet subscribers can use dsl-cache.saix.net port 8080 as a proxy server in their browser settings if they need to access the SANRAL website.
Of course, one wonders about the wisdom of launching e-Tolls in December, when so many people will be on leave or holiday just when teething problems like this (and I assume many others) will arise.
