Seeking VPS providers for low volume network probe

[ekgermann at cctec.com (Eric Germann)]

Greetings, 

I'm looking for recommendations on a reliable VPS Provider(s) who can
provide 

1. Centos 6
2. IPv4 and IPv6 (preferably) 

physically in the regions of African Continent, Eastern Europe/Russia,
Middle East, South America and Canada. 

I've already deployed some globally with Vultr and Amazon (Brazil
region). 

Basically doing a low volume test point probe (512MB-1GB RAM, < 20GB
disk) for latency measurements. Would prefer to have a secure (logically
and financially) and reliable host. 

Thanks in advance,
