[tor-relays] Relay requirements

[Sydney]

Newbie here. No network experience but already running 2 TOR instances: 1 TOR 
service + 1 bridge.

I would like to "upgrade" to TOR relays but have a few questions relating to 
hardware needs.

The [TOR-friendly] ISP I'm looking at have these 4 offers available:

[1]
1 core @ 3.1GHz
1 GB RAM
10 TB/mo @ 5 Gbps BW

[2]
1 core @ 3.1GHz
2 GB RAM10 TB/mo @ 5 Gbps BW

[3]
2 core @ 3.1GHz4 GB RAM20 TB/mo @ 5 Gbps BW

[4]
3 core @ 3.1GHz
12 GB RAM30 TB/mo @ 5 Gbps BW

From [relay 
requirements](https://community.torproject.org/relay/relays-requirements/), my 
understanding is that [1] is what is expected for a guard or middle relay and 
[2] for an exit relay.

My preferred choice at the moment is [3] where I would like to have 3 relays 
(one of each type; 3.5 GB RAM needed). Each relay would be limited to, say, 6.6 
TB/mo BW. This would allow me to experiment and get used to the network and its 
requirements.

My questions is about future increase. If I want to increase my offer to the 
TOR network I could:

- Negotiate with my ISP to increase my BW to 30 TB/mo while still running on 
[3] and increase each BW limit to 10 TB/mo;
- Move my 3 relays on [4] and increase each BW limit to 10 TB/mo;
- Move my 3 relays on [4], add 2 IP addresses and 6 relays (2 of each type; 
10.5 GB RAM needed total), and limit each relay to 3.3 TB/mo.

I guess my fundamental question is what is the advantage of running multiple 
relays of the same type, on the same server? I see some operators running 
dozens of them, all in the same country, same ISP. Why not just a single relay 
running with a large capacity? Also, is there a requirement for the number of 
relays per core? (Maybe this is the answer to my question.) I know my bridge is 
currently keeping one core of my 2-core server constantly under load.
Thank in advance.___

[tor-relays] Australian relays

[Sydney]

Hi all

I currently run 3 Australian exits, and 1 non-exit, in the 
262E84A99F53AE1F6860267F7C5DA5B96E57A46D family.

Due to personal reasons I need to take the relays down, which is disappointing 
as they are currently in a unique AS. 

This will leave 6 Australian exits. 

I appreciate that Australia is a long way in terms of latency, and my relays 
have been fairly under-utilised even though they’re on a 100mbit (Adelaide) and 
gigabit (Sydney) network interface. 

I might be in a position to bring these back in 2019. Before I do, I just 
wanted to know if it’s worthwhile having the Australian relays as part of the 
network?

Cheers

Sydney

I run 3 exits in Australia, my main relay fingerprint is 
262E84A99F53AE1F6860267F7C5DA5B96E57A46D. They’re all nicknamed govtis. Two are 
in Sydney and one is in Adelaide. 

I haven’t had any issues running these relays. 

I’m also unconcerned about the potential Access Bill passing into law. There’s 
going to be a general election before it’s even debated in both houses, and we 
may have an entirely new government by that time. ___
