I've often been heard saying something that rhymes with 'clucking bell' when this happens.
Considering the servers new equipment, we believe the major lockups were caused by a defective memory stick or cpu. Since those were replace, it's been better. The datacenter however had 2 rare issues. I spent a great deal of time researching these guys before the move and based on my past experiences with some of the principles, as well as advice from others in the industry and their reputation on the hosting forums made the decision that they were the place to go.
I have asked 3 other companies for quotes, 2 of whom are members of MT so are familiar with our requirements. Right now, it looks like a great many of the established hosts are having problems, so I don't have an affordable solution within my reach.
We're right now at the $300/month hosting level. The income from from MT (all forms) plus money from my hosting business allows that level of expense.
To buy the server that would really handle the load is about $5,000.
Leasing (as we do) gives us more flexibility at a lower entry cost.
That server however would be about $600/mo at most data centers. I have a quote on it at $900/month. Well outside my 'pain' level.
Maybe if we had 500 paying members at $25/month........but....at that rate, I think we'd have 5 paying members.
So, right now, I can just research and wait. But, it -will- be fixed.
