That is just nonsense. I have been using Dreamhost for over 6
years and have been up and running 99.9% of the time. 5 nines it
is not, but then who is?
By my math, 99.9% uptime would be less than nine hours downtime in
a year. On July 22, the entire DreamHost data center went down for
almost nine hours. The next day, their entire network went down
for twenty minutes. Yesterday, their entire network went down for
five minutes. That's already less than 99.9% download for the
year, only looking at the past week. I don't know about the
previous five years, but DreamHost has not had 99.9% uptime this
year. That's not according to me; that's according to DreamHost.
You can read it yourself:
Unlike many other hosts, DreamHost has no uptime guarantee, so
they're not even claiming to be reliable.
Any host that tells you they have an uptime guarantee is lying to
you. I used to be a systems administrator at a hosting company. We
averaged around 97% uptime on our windows servers. While some of
that was patching, most of it was downtime from our upstream
provider. There were a few cases where verio and uunet were both
down and we had no internet connection. Another thing i've noticed
on this thread is that people assume a hosting company is down when
they can't get to them. What about traceroutes? Sometimes its just
your path to the hosting company that is down and not the host
itself. Our main hosting box showed 98.4% uptime internally. 99.9%
is not possible unless the company has more than 3 upstream
providers, ups/generators, never patches their operating systems, and
does not cluster.
When you look for a hosting company, security should be just as
important as price. No one wants a hacked website. Its bad for
business. Most hosting companies have very old versions of software
like apache, php, and so on. Take that into consideration. It
doesn't matter what operating system the company uses. Mac OS X can
be vulnerable just as linux, windows, solaris or freebsd can. My
former employer was hacked at least once a year through the dns
server or one of the linux servers. Luckily none of my windows
servers were rooted, but I had to do serious patching and constant
monitoring.
