When you know whom you are targeting, it becomes easy to select the server/location to host your site. If your specific audience is from Poland, the server located in Poland will definitely make sense. The visitor will have your site content loaded from their nearest location.
AccuWebHosting provides Dedicated Server in Poland starting at just $75/Month which will have
- Intel Xeon E3-1245 v2 (4c/8t, 3.4 GHz)
- 16 GB RAM
- 2 x 2 TB HDD (With SoftRaid)
- 3 TB Bandwidth / Mo
- Free DDoS protection
- and much more…
I believe this will definitely fulfill your requirements. Though, if you have any concern, you can contact them anytime. They are top on the list when it comes to support/sales inquiry with their 24*7 communication channel.
Your target audience is Poland doesn't mean that you should go with a Poland server only. You can choose Dedicated servers in other locations too. You just don't need low latency but high performance, uptime, DDoS protection, etc.
