Internet Service Providers

Previously We had 4 Internet Service providers and 5 bandwidth links but has been reduced to 3 ISP/bandwidth for better streamlining and cost-effectiveness.

  • GLO -30Mbps (Decommisioned)
  • Etranzact-30Mbps (Decommisioned)
  • MTN-155Mbps
  • 21st Century-60Mbps (Upgraded to STM1)
  • NgREN (STM1 Connection/Shared Internet Bandwidth)
  • 21st Century via Google-25Mbps (The GUAP Project Router is to be decommissioned Aug. 2014)

 

VLANS
