Millions turned to Twitter to vent frustrations about the Blackberry crash A few hours after Blackberry maker RIM said all services were "operating normally" users have complained of a new crash.
The initial blackout saw Blackberry services across Europe, the Middle East and Africa disrupted.
Vodafone Egypt said it had seen partial disruption of services.
One tweeter summed up the mood of many: "Blackberry server down AGAIN?!!! you have got to be kidding me!!!!!"
Many called on the phone firm to "sort out" the problems and get the network running again.
The crash comes only a few hours after RIM had issued a statement which said all services were now "operating normally".
That blackout left millions of users without email, web browsing and messaging services following the crash around 11:00 BST on 10 October.
The cause is believed to be due to server problems at RIM's Slough data centre.
Details about what caused the stoppage are scant. In its statement RIM apologised for the inconvenience but gave no further information about the genesis of the problems.
Blackberry users around the world began reporting problems with their handsets mid-morning on 10 October and at 14:42 BST, Blackberry UK sent out a tweet which said: "Some users in EMEA are experiencing issues."
The "issues" left many Blackberry owners only able to text and make calls.
Serious outrage
Many corporate customers said they had not lost service, suggesting that the problem was with Blackberry's BIS consumer systems, rather than its BES enterprise systems.
"Blackberry runs two infrastructures," explained Simon Butler, a Microsoft Exchange consultant at Sembee.
"The understanding I have is that the BIS service has crashed.
Such a major failure will still come as unwelcome news to Blackberry's owner RIM, which has been losing market share to smartphone rivals - in particular Apple's iPhone.
Many corporate clients have switched to the device after Apple made a concerted effort to improve its support for secure business email systems.
"If you have got companies that are shifting their allegiance to other players in the market and you stop being able to provide them that concrete, reliable service, then that's going to have a detrimental effect," said Stuart Miles of Pocket-Lint.com.
The first signs of trouble emerged about 11:00 BST but seemed to have escalated with tags about Blackberry and its BBM service trending on Twitter.
In an early report, the Daily Telegraph quoted one Twitter user as suffering "serious Blackberry outrage".
Others lamented the loss of the free BBM network saying they did not know what to do without it.
