am not a user of Cloudflare as I do not maintain any web sites.
However I do use the internet to visit sites where Cloudfalre is installed
I also use a VPN service.
On Sunday 1st July I suddenly started to get reCaptcha’s on many sites that I visited. These reCaptcha were extremely long - sometimes as long a five minutes of ticking off busses, roads or roadsigns.
Then I visited bitfinex.com and I got stuck in a Loop on ReCaptcha.
I initially raised a ticket with Bitfinex but then I switched my VPN exit point and everything worked again. On investigating I found this link via google:
I now suspect that this may be a problem that comes from me using VPN and the site has had a problem with an exit IP address that is used by my original choice of VPN server. Therefore as a defensive measure the reCatchtas started to get introduced and this affected me.
Can you confirm that this is what is happening so I can go back to my VPN service provider (as I assume one of their customers was bombarding some web sites with an automated script and so the reCaptcha’s were applied as a defensive measure).
