Maintenance Archives
The maintenance window has been completed and all servers are now back online.
We didn't get a chance to carry out our maintenance window over the weekend so it will happen today starting at approximately 11:30 GMT.
This will not include all of the software upgrades we had previously planned but will include some and therefore the window could last anything from 30 minutes to an hour.
It will affect Inca, Zapotec, Nazca, Olmec and possibly Aztec.
Aztec is back online and fully functional once again.
Just another reminder if you didn't see the initial post about this maintenance window, there will be a second one next Sunday which could be up to an hour as we run some software updates on Olmec as well as bringing Nazca back online and restoring UPS power to Aztec.
Olmec was brought back online just before 18:00 GMT as expected.
Aztec is suffering some technical issues and so has not yet been brought back online. We hope to have it back online within the next 30 minutes and will post an update then.
Just a quick reminder about downtime today when we take some of the servers offline for maintenance as per the notice on Thursday.
Olmec and Aztec will be going offline at approximately 17:45 GMT. The outage should last around 15 minutes if there are no problems.
Additionally Nazca will be going offline at approximately 17:30 GMT and will be offline for a week as we need an on-site server at an event.
This is an early notice that there will be some scheduled downtime for Olmec, Nazca and Aztec this Sunday morning. We need to alter the power network and so will have to disconnect some of the servers in order to do this.
We'll post an update shortly before we take it offline. The outage window should only be about 15 minutes, possibly even faster if there are no issues but then there often are in these situations.
Futher more there will be another outage approximately a week later in order to carry out further maintenance to the power network. We will also be using this window to carry out some software upgrades and so expect the window to last an hour.
Finally, in the time between the two maintenance windows we will be running on limited uninterruptible power systems and so while we don't expect to have any outages, if the local power does fail the servers will be taken offline quickly.
There is a maintenance window between 23:00 8 February and 04:00 9 February which will affect a few of our web servers. The actual downtime is not expected to be more than 15 minutes.
There will be maintenance carried out on some of the web servers on Friday 1 February. The servers affected are Sarah Jane, Jennifer (currently hosting this site) and Charlotte.
The window will be between 23:00 on the Thursday night and 02:00 on Friday. There should only actually be 10-15 minutes of downtime however.
First up we have finished the maintenance on Inca! We've restored all the data so data is now available once again as are all the other services.
Secondly this means that Inca is now running at gigabit speed (it was one of the few machines we have that wasn't yet) so you should see a slight improvement of speed.
Secondly, now that phrase one has been completed we can begin phase two - the work on Olmec. So although all the data on Inca is now available, you won't be able to access it via FTP as we're taking the FTP server offline :p.
Seriously, Olmec is being taken offline while we conduct some maintenance. We're making lots of hardware and software changes so it could be offline for an extended period of time. We'll keep you up to date.
We're finishing this maintenance window as we need some of the services back online. As usual there are a few complications though (would we really have it any other way with computers :p).
We're half way through getting everything set up. At the moment we have brought all the services up so all the communication services are back. The only thing we are missing is the data store due to the hard drive replacement (as I write the new one is formatting).
If all goes well we shouldn't actually require any more downtime as everything we need to do now can be done while the server is live. Watch this space for more updates.
