The current system has 2.1x the single-core power and at least 4 times as much total power as the old VPS. And it now has 12 GB RAM instead of 4. Plus unmetered bandwidth.
The old VPS cost $40/month while home-hosting costs < $55/month. It's an extremely good deal, although it may take 2 weeks for HammerHost to "stabilize" and the outages to go away.
Yeah but the node the vps was on was looked after, expansion would be easy.
Anyway, for $41, you can get a reliable VPS with guarenteed 6 cores at 3.2GHz, 16GB Ram, 800GB disk space on a 100Mbit/s line with windows server 2008 on. Thats cheaper than hosting at home and infinitely more reliable. It's a no-brainer to be honest.
That's server class hardware. Desktop class hardware is not designed to be run constantly, hence why it keeps failing on you.
