Begging ComputerI have seen several sites reporting that the Google Calendar is going to be down nearly all day tomorrow. This is actually a misconception that came from an email Google sent out to Google Apps subscribers:

We wanted to inform you that we are planning to conduct routine maintenance to Google Calendar between 8AM and 9PM on Thursday, April 26th, 2007 .  During this time, this service may be unavailable to some of your users.  Please inform your users about this planned maintenance appropriately.  We apologize for the inconvenience and appreciate your patience as we work to improve Google Calendar.

If you have any questions, you can contact the Google Apps Support team through the Google Apps Help center (

The Google Apps Team

Please do not reply directly to this message. Please contact us through the Google Apps Help Center ( if you have any questions.

When I received the email I began wondering what they meant by maintenance? I tried contacting Google, and then before I could get a response back they sent a follow up email that included the following clarifications:

Why are we doing an upgrade?
We are updating some of our servers as we continue to improve Google Calendar. This is a normal maintenance update, and as with all updates we look to minimize the impact to our end users.

How will this impact my end users?
The impact to your users should be minimal. Only a subset of your users should be affected by the upgrade. These users may have trouble accessing their Google Calendars for a short period of time, generally less than 5-10 minutes each.

Will Google Calendar be down from 8AM to 9PM PDT?
No. This is the window of time that the maintenance upgrade will take place. During this time some users will experience issues accessing their calendar, but only for a short period of time each.

So if you’re a Google Calendar user you don’t have to worry about not being able to access your calendar for the 13–hour period that some people are reporting. What I don’t like is that Google only sent this message out to Google Apps subscribers, and typical Google Calendar users aren’t receiving the notification. The least they could do is put some kind of warning on the Google Calendar site itself so that everyone can be aware of what’s going on.
