[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.
Since about 10:00 AM UTC this Sunday (12 Nov. 2017), Dareboost is facing issues for websites tested from Paris and Amsterdam.
Only websites using resources from Google domains are affected (Google Analytics, Google Fonts, etc). As these resources are very frequently used, numerous websites are affected by the issue. Consequently we’re communicating with details on the issue, although the issue is out of our reach (the connectivity issue does not depend on our infrastructure).
All our team members are mobilized and we’re doing our best to get this issue fixed as soon as possible. Continue reading Incident: no response from Google domains for Paris and Amsterdam probes
