Incident: no response from Google domains for Paris and Amsterdam probes

[08:45 PM UTC]UPDATE : the network issue seems to be fixed now, we have removed the temporary blacklists and are monitoring closely the situation.

Performance and security of target=_blank links with rel=noopener

About one year ago, we were announcing an update of the quality checkpoints of our website analysis service. This update was including a new best practice related to hypertext links opening in a new window or tab by using target=”_blank” attribute.
Joining Google Chrome, the latest Firefox version now supports the rel=”noopener” attribute, which was one of our advised solutions. The right time for us to have a look back on this recommendation we have brought not only for better security but also for web performance. Continue reading
