Re: [bitfolk] 2011-02-26 1700Z onwards - scheduled maintenance for customers on curacao, faustino, kahlua, obstler, urquell

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.
