Hi All,

When IT does its next planned maintenance on June 20, we will be able to direct the Commons to a custom maintenance URL, but we won't be able to do that for people with mapped domains.

We should write to all of those people with two points:

1. An alert about the upcoming maintenance and planned downtime;

2. A note that if they want visitors to be redirected to the custom maintenance page, they should follow these directions:

-- change their DNS records to substitute a CNAME recordè for the A record è This could be a permanent, one-time change.

I've just shared the spreadsheet with you. Scott, if you could draft an email with Boone's advice on #2 above, I will send it out from the Commons address. Let's see if we can get this done by next Tuesday the 17th. Thank you.

Sorry -- had some extra text there at the end of the description that I have now deleted, as I have already drawn together the list of mapped sites

Please do not tell anyone to move DNS records to CNAME until I've given the green light. I need to run some tests.

You got it.

Hi -
I created a (rough) draft of the email, and included the email recipients from the spreadsheet. Here's the link -

Thanks very much, Scott -- that's a good start. Boone, please let me know how to handle the CNAME/A issue and I will move forward.

I've done some tests, and it seems as if CNAME mapping is working fine. I think we'd tested in the past and had problems, but it must have been a config issue.

Scott, let's please update our official recommendation: when mapping a domain name, point CNAME records to No change should be made to A records.

The email that goes out should make clear that the CNAME record replaces the A record. (A will take precedence if it's present.) I've updated the text of the email to be a bit clearer about this - feel free to change the wording as you'd like.
