Updated: Twitter has since reported that the issue was resolved.
The fail whale is alive and well at Twitter this morning.
"Some users may be experiencing issues accessing Twitter," the company reported on its status page today. "Our engineers are currently working to resolve the issue."
Downrightnow.com, which tracks the availability of Web sites, indicates that Twitter has been up and down for the past several hours. A similar site, Isitdownrightnow.com, shows that Twitter is currently up but notes that it was down earlier.
On my end, I've been able to access the site intermittently by refreshing it but did get smacked by the fail whale several times. At least one CNET colleague was shut out of Twitter completely for a half-hour or so.
A spokeswoman for Twitter confirmed to CNET that some people are running into access issues and said the company will provide updates on the problem through its status page. And the company did just that.
At around 10:30 a.m. PT, Twitter announced on its status page that the problem had been fixed.
We experienced intermittent issues affecting web and mobile users, globally, between approximately 7:00am and 9:50am PST. This incident has now been resolved. We apologize to users who were affected by this, and we're working to ensure that similar issues do not occur.Updated at 10:35 a.m. PT with Twitter's notice that the problem has been resolved.
