A couple weeks ago my shared office space upgraded to UFB. The building manager handled the entire process without consulting us directly on a detail based level. Most of us just believed that it would be better than our ADSL2+ connection.
So the provider was http://onefibre.co.nz they provide business only solutions and are not available to residential customers.
I got an email from our office manager stating the internet was switched over before I had headed into the office and quickly hurried on my way to internet of the future.
Upon arriving at the office I quickly fired up my computer and just tried to go to my website which is hosted on US servers and the page loaded excruciating slow. I then continued to do some speed tests and to my shocking discovery our international speeds were sub 1mbits both up and down. National speeds were great 100/50mbits.
The building manager directed me to talk with the UFB provider since they were right next door and they explained that we were on their "Sprint Starter" plan which has no committed international speed rates.
So to get good international speeds you have to increase your "Sprint Plan" and by doing so you get a higher international committed rate as well as a higher priority on international peak rates if nobody else is using the pipeline.
Their committed rates where shockingly bad. For $820 (gst exclusive) a month you get a 5mbit committed international transit. For 10mbit $1445.
In the end we upped to Sprint 1 which got us about 2mbit up and down during the day the upgrade alone was $89 a month and our internet speeds were complete crap compared to our shared ADSL2 line previously.
The poor building manager signed on a 2 year contract and unfortunately was stuck. The contract stated to terminate you had to pay the entire remainder of the contract anyways ( is this not illegal in NZ?? ).
In the end I bowed out of the office space -- I refuse to be extorted for internet to an ISP that is clearly taking advantage of confusing new tech and charging rates that are simply unacceptable. The charge was going to be $75 a month for 2bit up and down during most of the day.
So be careful when choosing a provider and if you can try to figure out what their contention ratio is so you know how much peak slow down you may be getting. Remember ISPs don't pay for GBs they pay for speed.
