Announcing: Office 365 endpoint categories and Office 365 IP Address and URL web service

Thanks Paul - still a bit confused though:

If you look at the RSS feed there's a publish date and an effective date and the effective date is in the future.

For example:

<item>
<description>Adding 1 IP_Set; 1/[Effective 9/1/2018. Required: Exchange
Online Protection. ExpressRoute: Yes. 23.103.144.0/20]. Notes: Adding an IP
prefix.</description>
<guid>18ef9105-dfb3-403b-bd50-29fe7106efa2</guid>
<link>http://aka.ms/o365endpoints</link>
<pubDate>Thu, 02 Aug 2018 09:46:50 GMT</pubDate>
<title>Exchange Online Protection</title>
</item>

 

So I assume this means on the 02 Aug we got notified of a change which will become effective on 01 Sep?

But if I look at the same thing from the changes rest call (I believe this relates to the same change):

{
    "id": 134,
    "endpointSetId": 9,
    "disposition": "Change",
    "version": "2018080200",
    "add": {
      "effectiveDate": "20180802",
      "ips": [
        "23.103.144.0/20"
      ]
    }
  },

 It looks like the pub date =02 Aug (from version number), but so is the effective date which I would expect to be 30 days later?

So with the rest service, does this mean that IP addresses will actually go live 30 days after whatever the effective date is?

 

Thanks
