We have, unfortunately, decided to postpone this migration yet again. For this we sincerely apologise.
The good news is that both of the issues identified last weekend were resolved. The bad news is that, while this migration will be quicker (once it gets going) with fewer complications than past migrations because of the fact that the new mail server runs newer versions of the same software, doing the migration this way actually introduces it’s own quirks and set of challenges. We really hope to address those over the coming week.
In the meantime, your email is operating as normal.
If you have any questions or concerns, please do let us know. Thank-you again for your patience.
We have decided to postpone the migration of server NC027 to NC036 until our regular maintenance window next weekend, 19:00 UTC Saturday (19 May) to 19:00 UTC Sunday. Of course, the move won’t take 24 hours, but that is the full length of the weekend maintenance window. Through testing of the migration process a few times on a test server and optimising the process of getting millions of email messages safely from one server to another, intact — this much data required a re-evaluation of our normal procedures — we have managed to shave at least six hours off of the planned migration time.
We therefore estimate that the migration will take about four hours.
There are a couple of reasons for the delay:
For now, everything stays and keeps working exactly the same. Do not adjust your television sets … or your email programs, for that matter.
Having worked with the new mail system all week, we are pretty excited about getting it online due to some new features and some excellent spam-fighting tools. We know you’ll love it too; thanks for your patience.
The migration later today of all mail from server NC027 to NC036 should take at least six hours, possibly more. For this reason we will try to start it a bit later than previously stated.
Due to an issue with the FTP server on NC020 we rebooted it at 00:27 UTC. It was back online at 00:28.
Server NC027 is being replaced by new mail server NC036. We will be migrating all email accounts to the new server during our regular weekly maintenance window next weekend, starting at 21:00 UTC on Saturday 12 May 2018.
We will be conducting tests over the next week to determine how long this should take, and will post an update here by the middle of next week with an estimate for how long your mail will be unavailable. Because this is a migration between servers running the same software, it’s much more straightforward that most migrations and should take less time than usual. Additionally, the configuration settings for your email will not change, making the process much smoother.
As mentioned last week, this is part of a two-phase plan — this is phase two — to significantly reduce downtime during migrations. Future migrations should be done in almost minutes rather than hours.
If you have any questions or concerns, please feel free to contact support. Thank-you for your patience.
Server NC023 was down between 20:06 and 20:23 UTC while a patch for the Spectre vulnerability was applied.
Server NC031 was down between 05:03 and 05:17 UTC while a patch for the Spectre vulnerability was applied.
The maintenance on server NC027 is complete, and it was brought back online at 22:17 UTC. Thank-you for your patience.
While we did this maintenance we also patched the server for the Spectre vulnerability. This means that the maintenance to do that on 1 May is no longer necessary, and has been cancelled.
If you have any questions or concerns, please contact support.
Server NC027 went down for maintenance at 21:05 UTC. We will post updates here as the work progresses and when the server is back online again.
