just for a ballpark figure to give you an idea:
http://www.df.eu/de/server-hosting/m...roduktdetails/ "managed server pro X8" 230EUR/month.
Currently maemo infra is using 5 servers of that power class (actually quite a tad higher: http://www.fujitsu.com/fi/products/c...gy/rack/rx300/ with 64GB RAM)
Of course we hope to massively consolidate that, but that's as well some job somebody has to do fulltime.

For operating such infra you need some professional administration 24/7 that's not for free either. For sure you need some experts to set up and configure the new infra and port the whole stuff from old servers to new ones and possibly new software (see e.g. vBulletin vs alternative solutions)
For now we have no hard numbers yet, but be assured $1000/month is for sure not a high guess when we plan to run all the maemo.org services on same level as they are right now (or rather been until some months ago when deterioration kicked in)

@reinob: we'll scale the infra to what we can afford, with wiki, tmo, and repos top priority. If money doesn't suffice to get powerful servers, you'll have to live with slow response times and "sorry, try again later". If we can't afford professional support, the whole system is on peril, due to threats from net and whatnot else. Please assume that board and council are doing their very best to ensure the infra for longer than just 3 months, but we can't give hard numbers yet since we're just starting. Buying another month for Reggie's server to allow painles migration to a cheaper server will cost ~500, a licence for vBulletin ~200. getting any new server may cost ~100..200 setup fee. And we still don't talk salary for a professional administration that does all the migration and bugfixing pending.
