8.8.8.8

[MDKza]

Hi all,

I thought these DNS servers were in the US.

Why am i getting local latency?

A tracert ends here google-public-dns-a.google.com [8.8.8.8]
Looks like this is googles DNS.

 

[themank]

So is 8.8.4.4

All you had to do was Google it to know it's Google's DNS. Easier than a tracert.

Those DNS servers are Google's. They are also cached here for better performance to our region, same applies for YouTube and various other Google services.

The 8.8.8.8 service is anycast. This means that there are multiple servers around the world with the same IP address and the Internet routers will (mostly) automatically route to the one that is closest.

The closest instance of 8.8.8.8 to South Africa was in Europe a few weeks ago. It appears that Google has upgraded their South African infrastructure to include a 8.8.8.8 node. I suspect that this has gone live in the last few days but I don't have any data to back that up.

Yeah, it has. As far as I know it's part of Google's infrastructure in JHB.

Noticed it last week. They have setup local nodes and its all about the routing to direct traffic to these new nodes. Awesome of Google making the internet a better place

Interesting, i'm sure this was international before

[etienne_marais]

Yay, now I can thrash open DNS for getting around partially propagated entries. (?)

 

[MDKza]

This is pretty cool.
Until this week it was sent overseas for me.

Same also realized it late last week as I use the servers for testing.

Traffic sniffing....?

 

[paul5186]

Google peers at teraco in jhb. Any ISP can peer with them. Your IPs get flagged as ZA, then if your isp peers with google the Google dns servers will resolve the query to the nearest local node.

 

[kianm]

Traffic sniffing....?

Its not sniffing its just routing. The ISPs update their routing tables accordingly. As per some previous post it seems MTN/AH have not done so yet so traffic on their network destined for 8.8.8.8 is still going overseas.

 

[Praemon]

I've opened a support ticket with Afrihost to investigate why it's still routing internationally with them. Would rather switch over to Google DNS if it now has local latency.

 

[MGRobinson]

Just for the fun of things, from different ISP's in alphabetical order (From Durban)

Discovered this last night when a ping to 8.8.8.8 on WA suddenly gave me a 30ms result instead of the normal 100-200ms. Was quite surprised to see the whole traceroute giving me local pings. Gives a whole new meaning to the world is getting smaller.
