UO Server/Shard Downtime FAQ

In UO, like every other software application, it's always a good idea to have a little downtime, as programs can start acting funny if left running too long.

So, the shards have daily maintenance times, and some of the other non-shard servers that perform services for the shards have weekly maintenance times.

Typically, these downtimes last 30 minutes (often shorter for the shards), but can be much longer, if there's an issue being addressed.

USUALLY, this goes off without a hitch - but on rare occasions (about maybe 1-3 times a year) something happens where a shard doesn't come back up, or other hardware issues interfere. When this happens, there will generally be an announcement on http://www.uoherald.com

At other times, there will be longer-than-normal downtimes for server publishes. These can be the major Publishes (numbered), or quick fixes for issues that come up (including exploits, etc.).

Such issues, if they come from a recent publish, can also result in an "unscheduled downtime" to do an emergency publish to correct the issue. These, too, will be announced - but often do not get announced in the web page until they are starting to occur (though messages are given in-game, that aren't always seen by the players).

Then, of course, there are system crashes, which are thankfully rare these days.

The Shard Servers back themselves up about every 45 minutes. They are timed to where they roughly coincide with the scheduled daily maintenance downtime for the shard, and the shard will stay up to the completion of the last backup started, before going down. Therefore, while the shard won't go down early, it may stay online a few minutes past its scheduled downtime, before it goes down.

There are 3 types of warning messages one can see before a shard downtime, in the game.

The first is the standard message that the shard will go down shortly, and that "You have approximately 2 minutes to find a safe location" to logout.

About 2 minutes after that, you will get the second message, that "the Server will be going down shortly". At that point, the backup is complete, and it's too late to get to a safe place (so you better hang around your machine to log back in as quickly as possible - especially if you have a pet out). There is a bug where a pet left out can wander off and be lost over a downtime, so you don't want to risk it - and you definitely don't want to have loaded pack animals out at the time.

The third type of message is rare, and comes about from Downtime that is out of the regular schedule. It is typically a message from a System Engineer or Developer that there will be an unscheduled downtime a certain time in the future, and this message will usually be repeated several times (With the time to the downtime being updated). When that time comes around, USUALLY, you will see the other two warning messages normally.

Scheduled Downtimes: When applicable, these times adjust for Daylight Saving Time.
