Thanks for the offer to become tier 1, but I'm not sure if a 100Mbit mirror should really do that in a country that large. We already have some rather fast tier 1 mirrors in the US. Keeping this open anyway, I'll decide later.

fine staying as a tier 2, if there are already a lot of faster mirrors in the region then that works, but my consideration is the locality of those mirrors within the US.
Do any of the mirror lists have region support more granular than the Country?
Judging by the organisations running Tier 1 in the USA, most are on the east cost or far north. The only one I can't nail down an accurate location for are the kernel.org mirrors.
In the end, may not make a difference as the average user will likely not select a tier 1 manually, but it might be worth considering for syncing purposes due to the hazard of update sources being in the same geographical regions.

Currently I'm syncing off of RIT. However, in an event like Sandy, RIT and NYU would both be at serious risk. The UGA mirror is on the coast as well, and I don't know where kernel.org's are. he Michigan mirror is not in a particularly hazardous region geographically as far as I am aware, however this would put a strain on them if they end up being the only one safe for continuity purposes.
I'm not really suggesting me being a tier one due to speed, but rather just to get some extra regional coverage and provide an alternative syncing source.

Another solution to the same situation would be a mirror bouncer that supports rsync. I've user mirror brain, but I don't know of one that does rsync effectively. If there was an rsync bouncer, then the situation could be resolved such that rsync updates can resolve to an available host for mirror admins, rather than script to a single tier 1 mirror (I'm personally working on scripting this check for myself, but maybe something like a round-robin DNS with a ping check would work well for this purpose?)

EDIT: Clarified statement of geographical situation for Michigan mirror.

So far our system worked well enough, but I agree that better geo information might be a good idea. I'm not so sure if we want bouncers since those are also a source of failure.

I don't have too much time right now, but I might try to write a script that uses geoip to figure out where our mirrors actually are (our database only stores countries). If you want to you can also do that. This should contain enough data to extract all URLs and then do the necessary lookups: https://www.archlinux.org/mirrors/status/json/

if I get my script working I'll share it here, or open a new request.

I could provide a mirror in Dallas hosted in Vultr dc, same as http://buywebtrafficexperts.com/ server.
