Can't access Internet Archive (archive.org):

[anterotesis]

Since some time today, I haven't been able to access the Internet Archive via my Three broadband.

I get the message:

Secure Connection Failed

An error occurred during a connection to archive.org. Peer received a valid certificate, but access was denied.

Error code: SSL_ERROR_ACCESS_DENIED_ALERT

Site does work on my 3 mobile connection, and on other broadband connections. Is this a problem at 3s end, or Internet Archive's end?

Changing DNS to Google's fixed the problem. So definitely something wrong with 3's settings.

I tried this on Chrome on my phone and I got the same error.
Altough when I try the same on Firefox I'm redirected to the following page https://www.three.co.uk/support/internet-and-apps/accessing-and-blocking-adult-content and if you scroll down there is a section "Sites being wrongly filtered"

@anterotesisfyi I received the following reply after I emailed them

I have just allowed adult content on my three plan, and I still cannot access archive.org. What do I do?

update: turned my wifi device off, and then turned it back on. I can now access archive (and other adult content)

Very unlikely, as the connection fails on different browsers when on 3 Broadband, but works when on another providers broadband.

Hi

You forgot another possibility, your browser settings

And imo this the only cause. So no problem with internet archive nor provider
