Gmail under Denial of Service attack?

Posted by Pelle Fri, 14 Oct 2005 06:58:00 GMT

Last night my GMail account started acting funny. It wouldn’t let me communicate with the server. After a few hours they seemed to get it working again, but I didn’t seem to be getting any mail. I sent various test messages that never came through.

This morning it’s the same. I’ve done the standard geekoid telnet port 25 to various of their smtp servers and they just timeout. So what is the story here? A DoS attack or something like that?

It seems something happened so they had to first just shut everything down. They then managed to get the web part of it up and running so people could access their existing mail, but not the actual incoming email infrastructure. I have been able to send mail from Gmail, which sounds to me like their infrastructure is actually working.

Hmm, a massive DoS seems the most likely cause. I hope they let us know afterwards what it was and how they (hopefully will) beat it.

Until GMail works again, if you need to reach me for any reason cc my account at pbraendgaard@mac.com as well.

Update After a brief loss of the web interface gmail came back around 5pm Danish time and most of my new incoming mail was ready and waiting in the mailbox. Still haven’t seen an explanation anywhere.

    Looks like Gmail has been suffering from some kind of outage since yesterday. Whenever I visit the site I get a 502 error (Bad Gateway). I wonder what is happening? I notice that a Technorati search or an Icerocket search aren’t really revealin.....
