Ads have disappeared

Across several sites, languages, accounts,

[Freedom]

It seems I can't get an ad to show up across 15 sites I own or help manage. F5 and refresh don't work, neither does turning off my firewall.

IS their adserver having a problem?

To be sure, I check my account to make sure I wasn't kicked out or anything.

Anyone else seeing this?

[javahava]

also seeing this; no ads appearing.

[Jenstar]

I haven't seen any problems over the last hour or so.

<added>Where are you located?</added>

[javahava]

located in massachusetts. the websites mentioned in the case studies on google's adsense page also don't seem to be showing ads; maybe the problem is geographic.

[Jenstar]

Are you getting any kind of error at all? Are PSAs/alt ads showing instead? Or just an empty space where ads should be?

[driris]

i can see the ads here in uk

[ypsites]

I've got empty spots, too. No PSAs, just nothing. My heart skipped a beat ... glad to know it's not just me!

Don't worry. They will be back.
