I'm serverloft.com client since 2008.
Over the years spent more than $5,000 USD for their services.
Experiencing a different problems - dead PSUs; motherboard replacenet; disk replacement; server replacement.
The last 2 years i'm using the VPS with 12GB of memory (44 euros a month - price as iron server OVH, Hetnzner etc.).
Tentatively on February 12, some idiot from the support, changed VPS limits so that now makes shmpages 289562 - about 1GB instead of 12GB.
Today 18 February and the problem is not solved.
Arguments brought them prove incorrect VPS configuration, but they just do not understand OpenVZ (Virtuozzo) documentation.
The server does not operate correctly.
Tens of thousands of visitors are lost.
Lost profits are difficult to quantify.
I had to configure the services as if I have 512MB of memory but not 12228Mb.
do not work with serverloft and their brands:
They have a common support.
In support staff remains only idiots who break anything, that worked fine before.
