At 10 PM EST tonight we will begin the upgrade of our network to PHP 5.3. This security upgrade is required for many modern PHP applications such as WordPress, phpMySQL and Joomla. In order to be able to provide the latest applications and the security patches they require, PHP upgrade is required.
We will begin the upgrade process at 10 PM EST tonight and expect it to take roughly an hour. Between 10PM and 11 PM EST there may be intermittent outages on our web servers while the upgrades are being performed and services restarted.
We will upgrade this NOC post once all the work has been completed.
Update: 10:45 PM EST – Upgrade to PHP 5.3 has failed. We will attempt again shortly and update this advisory.

Earlier today we encountered several tempfail mail delay scenarios due to a piece of software relying on DSBL realtime blacklist that was no longer actively maintained. We have taken action to remove DSBL from our web hosting mail servers which has resolved any delays and is currently processing the mail backlog.
Note: The issue only applied to mail1.ownwebnow.com. It did not affect any other services, such as Exchange hosting or ExchangeDefender. The issue was resolved and there should be no delays on the network at this time.

We are currently investigating an issue on one of our pop3 hosting servers. It appears to be a complex issue affecting a number of accounts. We believe we are near bringing this component back to full functionality.
Symptom: Cluster is up and responsive but certain users are not receiving mail. (related to a corrupted journal on one of the SANs)
11 AM EST: Service restored. We are still researching the issue and will provide an update after the weekly maintenance this Saturday. This appears to have been caused by a DDoS that did not get properly picked up.

From approximately 10 AM – 2 PM EST, our shared mail hosting platform (mail1.ownwebnow.com) suffered a large scale distributed denial of service attack (DDoS). Everything is under full control now and we have been able to filter out the offending systems. Unfortunately, there is little that can be done in terms of scale and protection against a DDoS as we already have both Cisco and Tipping Point in place.
DDoS attacks tend to be flared up by the regular user activity, as the system slows down end users keep clicking Send/Receive and effectively flood the connection until it times out. Systems are back to normal and messages are starting to arrive in regular sequence.

Our virtual hosting network (mail1.ownwebnow.com) is experiencing performance issues at the moment. We are troubleshooting the problem but a performance profile has been unusually low since about 4 PM EST (GMT -5).
We will update this item as soon as the issue has been identified. In the meantime, we have added some extra horsepower to the cluster to keep it moving.
The issue is classified as critical due to the potential mail loss that can occur when the system loads across the cluster spike beyond a certain level and shut down the inbound SMTP channel. We do not expect this to happen but are working under the assumption that the further performance degredadation will shut the network down.
