From the past few hours the Gmail service is down. This is the message displayed when I try to access my GMail.
I tried to login to Google Talk (GT). To my surprise I was presented with a blank buddy list. No contacts were displayed in GT window but my status was shown as ï¿½Onlineï¿½
As far as I know Google Talk is dependent on Gmail for the following 3 reasons
- It logs into the mailbox and displays a list of new mails
- Contacts are retrieved from the GMail address book and are displayed in the Google Talk Window
- Save your chat histories
Now if Gmail service is down, definitely the above 3 feature are affected. But this should in no way affect the ï¿½Presenceï¿½ and IM capabilities. My presence status was shown as online and I should definitely be able to see the Presence Status of other people in my Buddy list. And Google uses the standard XMPP (Extensible Messaging and Presence Protocol) which in no way is dependent on the availability of userï¿½s mailbox.
I did try to dig up in Google Talk FAQ to see if this is mentioned as a constraint
This is the answer for What does Google Talk do ?
When you download and use Google Talk, you’re actually connected to the group of users on the Google Talk network. Because Google Talk supports open standards, Google Talk users can also talk with users of other service providers that support open standards.
Even the query on What system requirements do I need to use Google Talk? doesnï¿½t seem to suggest the availability of GMail Service as a requirement.
So I presume Google Talk/Jabber Client is bound pretty tightly to the GMail service. I am not sure how Yahoo or MSN behaves in this scenario, but definitely something to ponder over for Presence/IM implementation.
And as I am writing this post, the GMail service is up and so is Google Talk 🙂
