iPhone + Geolocation + P2P

Since Apple's announced new embeddable Google Maps for the iPhone, not to mention the new P2P support, perhaps it's not too much to ask to get a cool new proximity-based alerting system?

Such a system could be used for geocaching or even friend-finding (the real kind of friend-finding where you already know the person...)

TENET has new transit providers

The TENET traffic graphs show NTT as a new provider:

And a 10G interface, to boot! This is likely in preparation for the arrival of SEACOM, as TENET's international bandwidth is the current bottleneck.

Traffic on Datahop has been halved, and traffic on Telias is at a quarter to a third of normal rates. So they are either being phased out or being used as backup providers.

UCT permanent upgrade to 43 Mbps

The bandwidth test was obviously successful as UCT has upgraded their connection to 43 Mbps. Graphs at the usual place [notice the jump around 12.30pm].

ICTS has issued a remarkably restrained notice. Did they not trumpet this to the whole campus because:
  • it's a drop in the bucket compared to the demand?
  • they don't want to stimulate further demand?
  • they don't want any recognition?
Whatever the reason, we still look forward to the upcoming 1 Gbps temporary link for TSN 63 (UCT)

Google resolving locally

When resolving www.google.co.za from within TENET IP space, one now receives A records indicating TENET IP addresses.

There are still some holdouts - kh.google.com / mwx.google.com and mail.google.com still resolve to normal Google IP addresses. Perhaps they'll transition soon.

Wits trounces UCT

I'm not writing about sports now, but rather about Wits's recent climb to the number 1 position on the unofficial bandwidth rankings:

Their monitoring graph shows peaks above 60 Mbps, and TENET's order status page shows an upgrade of their backbone link to 57920 kbps.

UCT's monitoring page show the same old peaks, with an upcoming 43008 kbps link as a consolation prize. This is obviously what was under test over the last week or two.

And it's interesting to see a new 'five-thirds' formula mentioned. Taking UCT's international commit of 26 Mbps and multiplying by 5/3 yields about 43 Mbps. Fully 40% of traffic is expected to be local! TENET: how about showing some flow statistics to the IS Akamai clusters?
