Hi,
On the evening of Saturday 26th February 2011 starting from about
1700Z we will be taking part in maintenance to completely re-rack
all servers in one suite. Goals of this maintenance:
- Turn the rack around 180 degrees to improve air flow based on the
location of cold air ingress from the under-floor air conditioning.
- Adjust rack posts to allow better air flow up through the rack.
- Re-rack servers in a way that doesn't impede air flow.
- Install new power metering equipment.
This is expected to take several hours. It's difficult to be more
specific because it depends on how fast we are able to work;
obviously we will be working as fast as is safely possible.
Customers on the following servers will be affected because these
servers are in the rack that we'll be working on:
- curacao
- kahlua
- obstler
- urquell
Additionally,
- faustino
which is currently in a different suite will be powered off and
moved. This outage will be much shorter - should be no more than 30
minutes maximum. This will be done after the other work is completed
so it's not possible to specify a time.
How to find out which server you are on:
https://bitfolk.com/customer_information.html#toc_3_Which_piece_of_actual_h…
We will be performing a clean shut down of all VPSes, followed by a
boot again when servers are re-racked.
The following BitFolk services will be unavailable during the
maintenance:
- The old primary DNS resolver, 212.13.194.71
- apt-cacher
- cacti
- tracker
- wiki
The resolver outage means that it's important that all customers
configure use of the new resolvers that were announced here:
http://lists.bitfolk.com/lurker/message/20110124.233915.2c058600.en.html
Failure to do this will lead to very poor network performance during
the outage, because your first resolver will not respond at all.
If you are otherwise unaffected by the maintenance and assuming you
configure the new resolvers, the absence of the above services
should not impact the operation of your VPS.
We can't alter the date/time of the maintenance, but if this timing
is disastrous for you then please let support(a)bitfolk.com know and
me may be able to accommodate a move of your VPS to a server that
will be unaffected.
Cheers,
Andy

Hi,
At approximately 1400Z today host kahlua appears to have been power
cycled. It immediately rebooted and as I type the last VPSes are
starting again.
I am still looking into what has happened here, as no one was
working on the server or in the rack at the time. Please accept my
apologies for the disruption.
Cheers,
Andy

Hi,
You may recall recently that there was a period of poor network
performance because the customer DNS resolver on 212.13.194.71 was
overloaded:
http://lists.bitfolk.com/lurker/message/20110102.221800.b90128dc.en.html
In that thread I promised to provision a new dedicated resolver to
avoid a re-occurrence of the issue.
Instead I took the opportunity to provision several new resolver
hosts in a cluster with fail over for the service IPs.
All customers should change their resolvers from:
212.13.194.71
212.13.194.96
to:
85.119.80.232
85.119.80.233
There's some maintenance coming up in February (details in a
separate email, shortly) which will take 212.13.194.71 offline for
several hours. It's therefore important that you change to using the
new resolvers before this time, otherwise you will experience severe
network performance problems.
If you have any questions please direct to users list or
support(a)bitfolk.com.
Cheers,
Andy
