What steps will reproduce the problem?
1. Search for "www.dn.pt"
2. Open the first version of 2004: 9 Feb (http://arquivo.pt/wayback/wayback/id35066index0)
3. The archived page of 14 Feb 2005 is shown.
4. Go back.
5. Open the version 31 Mar 2004 (http://arquivo.pt/wayback/wayback/id36964index0)
6. The archived page of 14 Feb 2005 is shown.

The same behavior can be observed for every version up until 2006.
From 2006 to 2008, the same behavior happens with another archived version (http://arquivo.pt/wayback/wayback/20080212134236/http://dn.sapo.pt/).

Other archived websites present this behavior, e.g. "www.expresso.pt".

Here's another example:

http://arquivo.pt/search.jsp?l=pt&query=ipb.pt&btnSubmit=Pesquisar+no+Arquivo

6 Jun 2010 links to:  17 Dezembro, 2009
26 set 2009 links to:  17 Dezembro, 2009

There are also a lot of broken results:

6 Jun 2010 links to:  Resource Not In Archive
6 Jun 2003 links to:  Resource Not In Archive
22 Jun 2003 links to:  Resource Not In Archive
21 Mai 2005 links to:  Resource Not In Archive
10 Fev 2005 links to:  Resource Not In Archive

Still another one.

Searching for
mega.ist.utl.pt/~sinfo

http://arquivo.pt/search.jsp?l=pt&query=mega.ist.utl.pt%2F~sinfo&btnSubmit=Pesquisar+no+Arquivo

All versions from 2003 point to a version from 19 Oct, 2002.
Versions from 2002 up to 11 May point to a version from 02 May, 2001.
Versions from 2004 up to 19 March point to the same version from 02 May, 2001. Same for dates 23 May, 1 Sep, 24 Sep and 11 Dec, that point to 02 May, 2001.
It also happens for dates from 2005 and 2006, that still point to 02 May, 2001. I didn't check them all, but it happens, at least, with the versions from 31 Dec, 2005 and 13 Aug, 2006.

This issue seems to be more frequent than initially thought.
Changing to critical due to the fact that this issue misleads users and prevent the access to the relevant archived versions.

Version of 2006 redirect to versions of 2002

After further investigation, the trigger is redirection of archived pages. When they were crawled the redirect information was preserved. However, when replaying the archived page, they silently re-apply the redirection.

The big issue here is: why the redirection points to a page much older or much newer when a temporally closer version is available?

Example:
1. search for: www.dn.pt
2. click the version from "9 Fev 2004" (arquivo.pt/wayback/wayback/id35066index0)
3. the browser is redirect to the page "http://dn.sapo.pt/" from "14 Fev 2005" (http://arquivo.pt/wayback/wayback/id136index2)
- For "http://dn.sapo.pt/" there is a version of "9 Fev 2004" but that's not were the browser is being redirected to.

Example2:
1. search for: www.worten.pt
2. click the version from "11 April 2006" (arquivo.pt/wayback/wayback/id15068247index0)
3. the browser is redirect to the page "http://www.worten.pt/home.html" from 2 Aug 2002 (arquivo.pt/wayback/wayback/id39948470index0)
- For "http://www.worten.pt/home.html" the date closest to "11 April 2006" are "26 Jan 2006" or "12 April 2006" but the version of "2 Aug 2002" is opened.
