[AusNOG] Attempting to understand DC internet connectivity

[Richard Thornton]

Thanks Harry, stick to international per mbit in the beginning, got it.

To clarify:

-I already have stuff in SY3 colo through a reseller, I want to explore
going direct, relocating within SY3 would be nice (I think they do half
racks now).

-I already have an allocation from APNIC.

-Taking up to 1/2 a rack is OK.

-I plan to mostly consume content.

-I plan to grow the mbit/sec considerably.

-I would want direct 24/7 access to my rack.

-I like the idea of choosing my upstreams, adding local later and maybe
connecting in to AWS and Azure.

Newbie questions alert:

When you see pricing advertised like $18 per mbit for SAU colo (with
redundant upstreams), are they just passing on the massive discounts they
get for large pipes or is there some form of contention ratio going on,
they seem to be much cheaper than going direct with a single upstream?

If you had two upstreams and wanted 20mbit total from Vocus and Telstra,
how would you carve up the mbit for redundancy, have 10mbit from each so if
one fails you temporarily lose half your bandwidth (BGP wasn't that great
at load balancing can you even get a 50/50 split like that)?

Do upstreams generally support the creation of queues and receiving DSCP
markings on their border, so you could shape an IP coming from your network
to stop them consuming all your upstream bandwidth?

That's about it for now.

Thanks.

Hi Richard, on such low commits most providers won’t differentiate between
local / international or there won’t be much price difference or advantage.
It only makes a difference once your commit a lot higher.

Hello Everybody,



Newbie here, hopefully this hasn't been asked before (I couldn't see a way
to search the archives) so please be gentle.



Say I go direct to one of the big Sydney DC providers and take up whatever
minimum RU they require, say it's Equinix, it looks like I can take their
(already highly redundant) internet product or I can bake my own by peering
with other (national and international) upstream providers that I choose
and Equinix will cross connect me to them, is that correct?



What would be the (very) rough setup costs involved and per mbit / per
month costs for say 30mbit (combined 2 peers international and 2 peers
national, I ask this because I don't think most DC internet products
separate international and national) or 10mbit (2 peers international) /
20mbit (2 peers national) as well as any advantages/disadvantages of each
method? (in both cases assume I have the equipment and expertise to install
and configure it all).



Apologies if I haven't asked this properly, essentially what  I am asking
is whether it is considerably cheaper to build a resilient internet
connection by buying direct from upstream peers like Vocus for such low
bandwidth, is it even possible, do they have a minimum bandwidth
requirement for customers?



Thanks for looking.



Best regards

Richard
