Hi all, Today I have a dedicated, non managed, server on Hetzner. I pay a small company to keep an eye on my server and sometime I ask for their support. For example, I asked them to make daily backups on my dropbox (database and files). The thing is that my users are all in Latin America and the server is in Germany. Server is awsome, but the ping is high. I'd like advice for: 1) Best/cheap dedicated hosting in USA. Constultant should measure server numbers to see what type of server I really need; 2) The new hosting has to be managed, since I'm not a system Manager and I want to stop to have that fee (of course my hosting will charge for that). I mean, I want the hosting company to manage the server. 3) Has to have Cpanel or any other control panel for me to use; 4) SSH is important; 5) Need advice on using CDN (best company) and measure the cost I will have montly (i can send the montly brandwidth). 6) Any advice that would nelp my SEO; 7) Server is linux; Please send the questions needed for me to answer if you get the job. Thank you. I'm probably forgeting something. :)

I need my social network website optimized for speed for logged in users. I have a Wordpress (Buddypress) website that is built on a Linux VPS using mod_php handler on the Wordpress side I am using W3 total cache and Cloudflare as my CDN . The site runs at a decent speed for non-logged in users as is, but is very slow for logged in users and takes a long time to post user update or create groups etc.. I do not care what type of configuration the server or wordpress uses as long as its fast for logged in users. That being said I would like some type of cache setup ex. (fragment cache,opcache,zend cache, Xcache,eAccelerator), however if FastCGI is as the php handler used it would need to have a limit on the amount of ram it can use to cache. This will need to go hand in hand with the wordpress side and CDN if nessary.

Hello, I have a number of Wordpress sites running on Nginx on Unix in the Amazon cloud environment. I am currently using one security expert who is having trouble locking down the site. He is more of an analyst and does scans and adds plugins and looks at the Unix server settings and Nginx settings, but he is not a programmer and he is not very fast. What I am needing is someone who fully understands php code issues as they relate to the typical exploiting problems, like SQL Injection, XSS, CSRF Injection and more; AND knows how to fix them (modify the code without just throwing the code out completely), to plug the holes so there are no more exploitable holes. I would prefer if you are also an expert in Nginx and Unix and the Amazon back end. There sites are live in production sites and need to be secured and maintained. Thanks!
