Google Postini Service Update: 10/14 11:45 AM ET

The following is the latest status report regarding the Google Postini Service problems, as of 4:45 AM ET this morning:

"We experienced an issue that caused significant delays to inbound mail delivery for users on System 7. Postini Engineering and Operations have resolved the issue, and mail delivery rates have returned to normal. Engineering and Operations continue to closely monitor the situation.

During this incident, incoming messages may have been deferred; no messages were bounced or deleted.

Some sending mail servers may have returned a "failed delivery" notification after four hours, but continued to try to resend deferred messages (up to five days for a typical configuration). Outbound mail delivery and filtering performed as normal during this time.

We sincerely apologize for the impact to your organization and users. We will post an incident report, which includes the root cause analysis and corrective and preventative actions, within the next 48 business hours. Also, if you filed a support case, we will include the incident report in the case response."

Horizon expects that some users may continue to receive delivery of emails that were deferred, or that were resent by protocol from the sender, throughout the day.

As your reseller, we have access to the portal and will post the incident report when it is available. Please contact support if you have questions or concerns.

Google Postini Services Update 10/13/09 11:00 PM

At 7:15 PM ET, an update was posted for Google Postini Services:

'We experienced an issue which has caused a backlog of inbound email affecting
users on System 7. We are currently taking steps to address the existing backlog
and minimize the impact on new incoming email. For the affected users inbound
mail has been flowing but at a reduced rate. Outbound mail remains fully
functional. We are working to fully restore mail flow as soon as possible, and
we will provide ongoing updates.'

As of 11:00 PM ET, our observations are as follows:

• Services are running normally via the Secondary Data Centers
• New messages are flowing with little apparent delay
• Deferred messages are being released into the stream
• The message center and administration console are both available for use.
• This remains a 'no data loss event'
• Spooling is functioning properly"

We updated our home page to refresh recent blog posts at 5 minute intervals. We will continue to post information as appropriate.

Google Postini Service Update: 6:20 PM ET

For our customers, mail flow for Google Postini Services has been "normal" since about 3:25 this afternoon. A short while ago, the Message Center and System Administration consoles came back online.

The Postini service will continue to add deferred messages to the stream of messages being process and delivered in real-time. While we have no official word about how long it will take to forward all of the deferred messages, we expect the process will take several hours.

We will continue to monitor the process and post updates as appropriate.

We certainly understand the frustration and pain that accompanies email service disruptions. We appreciate your patience and understanding.

Google Postini Service Update: 3:00PM ET

Google Postini Services continue to experience mail flow problems. Mail flow rates continue to swing between Normal and Critical this afternoon.

Horizon's customers site on Postini's "System 7", which is now operating out of secondary data centers. This shift should improve mail flow as the systems forward deferred messages.

A status update posted at 2:40 PM ET indicates significant progress in improving mail processing.

Note: During this time, messages may be deferred or queued, but no messages will be lost, deleted or bounced. Mail processing may also be directed to the secondary data center at times.

Given the nature of the incident, we expect mail flow performance will continue to fluctuate until the issue is fully resolved and the backlog of email is delivered.

We will continue to post updates as they become available.

Some users are still experiencing intermittent delays in email delivery through Google Postini Services. Currently, mail flow is at near normal levels. Emails will still be delayed as the service forwards queued and deferred messages.

Given the "fast/slow" nature of this event, we expect that mail flow rates may continue to fluctuate this afternoon. We will post another update as information comes in.

SPAM Continues to Trend Upward;

So how do spam trends related to cloud computing? It all depends on how you block and fight SPAM.

According to the Q2 2009 Spam Trends report published by the team at Google Postini Services, spammers have developed means of releasing days worth of spam in just hours. If you are manage spam from within your network, this means your Internet connectivity and servers are more susceptible to performance degradation and failure.

Across our customer base, ~92% of email is spam. Most spam is sent to invalid email addresses. This traffic chews up bandwidth inbound. If it hits your servers, it increases the disk space used for log files as well as outbound bandwidth for non-delivery report messages.

If you stop spam in the cloud, you protect your network and server performance regardless of the volume of spam targeting your domain.
