New Delhi: For at least the third time in 11 days, Google's Gmail users have encountered 502 errors while trying to access their emails. The first reported Gmail downtime this month was on May 2, followed by another on May 8.

Trying to access Gmail, a message on the page said, "502. That's an error. The server encountered a temporary error and could not complete your request. Please try again in 30 seconds. That's all we know."

502 errors usually happen due to poor IP communication between servers. There have been a number of previous occasions when Google users have encountered a similar error.

In regard to the "Error 502", Google's support page describes, "whenever you're see a 'Temporary Error (502)' message when you try to sign in to Gmail, it means that your mail is temporarily unavailable. These errors generally resolve themselves within a few minutes, so please wait a bit before trying to log in again."
