Starting in the first few days in April 2016, Barracuda operations and customers may have observed a slight delay in mail traffic that went through our Barracuda Email Security Service (BESS) or our Cloud Protection Layer (CPL). While this is partially due to a spike in new customer traffic (which is always a good thing) , this is also primarily being attributed due to an uptick in ongoing spam campaigns being actively operated around the world noticed by many security firms.
This unexpected traffic has caused our Email Security Service to work harder than ever and as such, some customers may have been observing delays in their email that is filtered by our cloud services, including a delay in receiving email messages, or quarantine notifications being sent out.
To combat this we have added additional service VIPs to multiple data centers to distribute the load being seen, as well we are planning further expansion into additional data centers based on geographical options.
Note: With the addition of new IPs to the BESS service, this may have inadvertently caused some traffic to become grey listed as SMTP traffic was seen on IPs not recognized by other services previously, but should resolve itself eventually.
As of today 4/13/2016 Barracuda believes we have resolved most instances of this, however If you feel you are currently experiencing an un acceptable delay of sorts - please contact support so we can gladly help in reviewing this asap.
As always, Barracuda wants to say thank you to everyone who allows us to continue to be the worlds greatest network security vendor and allowing us the time to further enhance their Barracuda experience while delivering further award winning products
