FYI just received this e-mail from my host provider.
July 18, 2011.
Please be advised that we will be migrating your web hosting account to a different server sometime within the next three days in order to avoid a lengthy period of downtime this upcoming weekend. (Semi dedicated and dedicated server clients are not affected.)
Reason:
One of our data centers has informed us that they will be moving all of their equipment, including our servers, to a new location on July 23 in order to satisfy their growth requirements. The move is expected to take anywhere from two to eight hours to complete and that is far too long of an outage for us to not take immediate action.
Impact:
Accounts will be moved from the affected servers onto existing servers at our other data center starting tonight. The whole process should be seamless with no noticeable downtime, however, performance may be suboptimal until we redistribute accounts to others servers and help spread out the load.
We were caught off guard by our data center’s plans so please bear with us while we attempt to maintain service without any disruptions.
