I've been with adsense for about 2 years now and I've never seen an increase like this ever before. My eCPM suddenly shot up by over 100% in the last 24 hours. My site gets very high traffic and clickthroughs (6,000 clickthroughs + per day), so this isn't just some anomaly due to low traffic. Has anyone else experienced this? I'm not complaining, I'm just in shock right now.
