I got this message repeatedly for about 10 minutes earlier this evening when trying to get to google.co.uk. I checked other domains, like google.fr, which seemed okay. Then I got kicked out of Gmail in the middle of a chat exchange and was prompted to log in again. Did anyone else notice anything strange with Google at around 8:30 PM UK time? Everything seems to be fine again now.
UPDATE @ 11:05 UTC: Mega-uber friend Thomas Anglero up in Norway has pinged me to say he hasn't been able to access his Blogger account since 10:00 AM CET, which means 14 hours of downtime. What is going on?
UPDATE 2: A Palladium Club mega-uber reader in the Netherlands also remarked that his Gmail was out of service at the same time.
