Tumblr help?

[Oniya]

So, Little Oni follows a number of Tumblr blogs.  Over the past few days, while she can see content in her dashboard, if she tries to access the individual pages directly, she gets an error from the browser saying that it can't connect (this happens in both Firefox and Chrome).  The pages are obviously still there (since the content is showing on her dash), but the direct access seems to have disappeared.  She read off one of the page urls to me, and I'm able to access it fine from my machine.  I know I haven't changed any security settings on her machine (and don't think that there are any that would apply - even though Firefox's error suggests 'making sure that Firefox is allowed through your firewall.'  Yeah, pretty sure if it wasn't, then YouTube wouldn't be functioning either.)

Anyone got any clues?

[Oniya]

Semi-update - it looks like a lot of people are having this issue, right down to the message about 'firewalls' (which shouldn't be able to affect individual blogs, without major tweaking at the computer, right?)

[Vekseid]

Since Tumblr blogs have their own subdomain, a local firewall can certainly block them.

[Oniya]

But you'd have to manually configure that, correct?  At the computer end (not the router, not the ISP)

[Vekseid]

Derp.

No.

The machine still sends out a DNS request, and the domain itself is requested in plaintext (though it's rare even then). Though this doesn't explain why she'd see it in her dashboard. You can try editing her DNS settings, though.

[Oniya]

Well, with absolutely no action on our end, things are back to working.  O_o  You think maybe adding an alternate DNS server might remedy this if it happens again?

[Vekseid]

If it is an isps issue, that can help. Sometimes their DNS servers die or whatnot.
