When high SEO ranking fails to give you a reliable result: IsItDownRightNow.com failed to detect the WayBack Machine outage
Posted by jpluimers on 2022/02/11
A high SEO ranking does not automatically indicate a reliable result.
When the WayBack Machine was down a while ago (it responded to traceroute UDP requests, but would not establish TCP connections on ports 80 and 443), the first Google hit for detecting down status (searching for [Archive.is] waybackmachine down – Google Search) failed miserably because it redirected web.archive.org (which fails) to http://www.archive.org (which succeeds):
IsIdDownRightNow failing to detect web.archive.org downtime
Luckily when asking around on Twitter:
- others were experiencing the same problem, not just in The Netherlands, but also in other countries
- after trying a few things, the WayBack machine got backup [Archive.is] before I could try cURL.
- I got pointed at www.uptrends.com/tools/uptime which correctly does check the right subdomain and shows it is down from many locations:

Highlights from the Twitter thread

A traceroute or tcptraceroute worked fine, but connecting to ports 80 and 443 failse

IsItDownRightNow does an incorrect redirect from web.archive.org to archive.org
This is just as bad as modern browsers hiding subdomains. Subdomains are important!

cURL was moot, as the site got up before I could try it
