continuous supply of the right amount of bandwidth to your server
is critical to its successful operation.
Resilient, Multi-homed Supply
Bandwidth provision to the Internet is a key component of hosting.
Supplies of bandwidth do fail on occasions and result in interruptions
or degraded performance for your business critical systems.
This is why EQSN has invested heavily in equipment and multiple
supply sources of bandwidth to provide a "failsafe"
bandwidth environment. We monitor and review the quality of supply
of bandwidth from all our sources, ensure that each supply is
mutually independent and select several reliable suppliers.
These multiple bandwidth supplies are fed into our network in
a triangulated, resilient form where our infrastructure ensures
that, in the event of failure of one or more of the supplies,
there remains a continuous supply of bandwidth to all our customers.
More than just providing telecoms from a number of different
suppliers, thereby providing a route for connectivity resilience,
our Glasgow and Edinburgh data-centres are connected to the Wolrd-IX
This means, for instance that traffic destined for other parts
of Scotland does not have to go to London and back again. In the event of failure of
one telco the systems will automatically switch through to another
telco, thereby ensuring the maximum potential Internet connectivity.
This is a key factor that often plagues other ISP and hosting
BGP-4 & Triangulated Schematic
This BGP-4 compliant, triangulated infrastructure ensures that
your servers will remain connected to the Internet.
Supplying the right amount of Bandwidth
Bandwidth needs frequently change. Special projects, steady increase
in usage, new product or service launches all generate changes
in demand for bandwidth. It is critical that you have the right
amount of bandwidth available when you need it.
This is why EQSN has made arrangements with Telcos to have open-ended
provision - allowing us to draw Gigabytes of bandwidth on demand.
On demand ensures that when we charge for bandwidth you only pay
for what you use and that you can take more than you are contracted
to. Often bandwidth requirements result in surges that may be
difficult to predict, our model permits this type of activity
and is geared to ensure you have the capacity when you need it.
In general terms customers contract to a baseline bandwidth that
should be sufficient to meet their average monthly usage. For
our calculations usage is monitored over a monthly period. Where
circumstances result in increased usage we calculate the usage
over the month and determine what the additional charge is and
if there has been sufficient traffic to warrant moving into another
There are 2 main measures for Bandwidth - Bandwidth and Transfer
The table below provides indicative comparisons of bandwidth and
the approximate equivalent monthly transfer volume.
