Science bandwidth requirements estimate

A recent e-mail from a Meraka engineer working on SANReN:

We know eVLBI would require a 1Gb all the way to Amsterdam, current projections for full SKA is 100GB international capacity, the MeerKAT project will probably require 10GB of bandwidth.

So something like the 'bandwidth glut' of Infraco would definitely be required.

It seems like the only people talking about having too many cables are those with a vested interest in having only a few [competing] cables.

Extra transit for TENET

Viewing the monitoring graphs for TENET's London node, a new transit circuit through DataHop [web?]is apparent:


Peak speeds are about 50 Mbps. Combined with the Telia peak of ~100 Mbps, this means TENET currently has ~150 Mbps peak transit.

Note the very small outbound. Mmmm, eyeballs.

Unscheduled scheduled outages

A recent posting to the TENET ren-news list:

All Neotel MPLS GEN3 sites experienced a number of service failures
early yesterday morning. It appears that these were caused by Neotel
maintenance, of which TENET was not informed in advance.

even given

The Service Level Agreement provides that: "...The Providers will give TENET four days' advance notice of planned maintenance."

Let's hope Neotel doesn't become Neotelkom [the new Telkom?] :)
