Network Maintenance Window Tonight

    We will be returning our network systems to normal fully redundant 
operating status tonight. Once this is done we will test the fail-over
and fault-tolerance. This may cause brief (1 to 15 second) pauses on
the network. The purpose is to ensure that all systems perform as
intended.

After the power incident yesterday, the M5Hosting "PremiumNet"
network systems performed in an unexpected manner. All systems have
been previously tested and performed fail-over flawlessly. This
testing to take place tonight is to make sure that this is still the
case, given the unexpected behavior yesterday. The unexpected behavior
yesterday took place between our border routers and AIS's routers
which face us when power was restored. Performing a test of the
fail-over systems tonight will help determine if the network issues
were due to the effects of the abrupt power interruption on the
network devices, or a configuration of the network devices. Both M5
and AIS Network Engineers will be on hand for this work.

The M5Hosting "ValueNet" was not affected once power was restored,
is running in normal operational status and should not be affected by
tonights testing.
The vast majority of our customers are on "PremiumNet". If you do
not know which you are on, you are most likely on PremiumNet.

Window Start: Friday March 20, 2009 02:00 US/Pacific (GMT -7)
Window End: Friday March 20, 2009 04:00 US/Pacific (GMT -7)
Duration: Customers on M5Hosting's "PremiumNet" may notice a few very
brief interruptions of a few seconds in length.

As always, I want to hear from you regarding this email, and how
we are doing... or anything at all.
