Occasionally outdated versions of Security Advisories are provided

[bynt]

Describe the bug We check the Security Advisory feed

https://technet.microsoft.com/en-us/security/rss/advisory

once every 3600s for updates. Since February 4th, ~2130 UTC we occasionally crawl outdated versions of

https://docs.microsoft.com/en-us/security-updates/securityadvisories/2017/4053440

in this way. Most of the time we get V3.0 of the advisory, sometimes we receive an older version.

To Reproduce Steps to reproduce the behavior:

1. regularly check https://technet.microsoft.com/en-us/security/rss/advisory for advisories
2. check individual advisorie's source code
3. compare certain parts of the source to last imported version

Expected behavior always get the latest version of each advisory

Screenshots n/a

Desktop n/a, only source code is processed

Additional context In the example given, the source code of the latest version hints at the use of markdown language for the content of the provided advisories, e. g. 'sourcefile', 'sourcestartline' and 'sourceendline' in

<h1 id="microsoft-security-advisory-4092731" sourcefile="SecurityAdvisories/2018/4092731.md" sourcestartlinenumber="1" sourceendlinenumber="1">Microsoft Security Advisory 4092731</h1>

According to tech team, these markdown features are not present in the source code of the outdated advisory we occasionally find at the same URL. Maybe there is something like loadbalancing involved and we occasionally receive

https://docs.microsoft.com/en-us/security-updates/securityadvisories/2017/4053440

from a server that does not know of markdown or didn't receive the (alleged) February 4th security advisory markdown update?

Edit The issue may also be related to Akamai's CDN services.
