PHP 5.3.15 is now available on all hosting accounts. It’s the default for new customers, and existing customers can update their PHP version using the “PHP Settings” link in our “My Account” control panel.
If you’re an existing customer using an older version of PHP, we haven’t yet changed your PHP version. However, we will begin doing that in about 30 days (we’ll announce that separately), so we recommend that you upgrade now. That way, if you find you’re using an outdated PHP script that isn’t compatible, you can set PHP back to the previous version and work to update the script. The old PHP 5.2 series will be removed from our servers by the end of 2012.

At 12:50 AM Pacific time, the web08 server experienced extremely high disk load and needed to be restarted as a result, resulting in approximately 5 minutes downtime for sites on that server. Other servers were not affected, and the server is now working normally.
Today at about 12:26 PM and 12:34 PM (Pacific time), our network was briefly attacked by an extremely high volume of data — a “distributed denial of service” (DDoS) attack using forged (“spoofed”) source addresses. The volume of the attack was more than 50 times greater than the usual peak inbound data rate to all our servers combined. This caused Web sites and e-mail we host to be very slow or timeout completely for a few minutes. (All services are working normally now.)
The same attack happened a week ago. Based on what we learned previously, we were able to trace the attack in more detail, and we have identified a specific controversial site that the attackers are targeting. We have moved that site to a different section of our network that can fail without affecting other sites, and we will work with the site owner to move it to a dedicated DDoS protection service.
We apologize for the problems caused by this incident. We know that achieving maximum uptime and availability is important for all of our customers.
Update 1:41 PM Pacific time: A contact at Level 3 Communications confirms that their San Francisco Bay Area network was disrupted by a “configuration error”, causing problems for a great deal of Internet traffic that passes through Level 3 (not related to us in particular). Level 3 has corrected the problem, so we’re marking this issue as “closed”.

We had a couple of brief network interruptions today (at about 8:50am and 12:49pm Pacific time). We are investigating them, and will update this post with more details later.
Updated 2012-07-19 2:23PM Pacific: One of our upstream network providers has traced this to what appears to be some very brief, very high-packet-per-second attacks. The attacks have not recurred, and we are continuing to monitor all systems.
The “web11” server became very slow and needed to be restarted at approximately 2:00 a.m. Pacific time this morning (June 25). This caused a brief outage for Web sites on that server. Other servers were not affected.
Between 11:00 PM and 11:59 PM Pacific time on Saturday June 23 2012, the MySQL database software on each of our servers will be upgraded to version 5.1.63 and restarted. This will cause an approximately 30 second interruption of service on each customer Web site at some point during this hour.
This upgrade is necessary for security reasons. We apologize for the inconvenience this causes.
Update 11:12 PM June 23: The maintenance was completed as planned.
Between 5:10 and 5:22 A.M. Pacific time this morning (June 15), one of our upstream network providers experienced a large distributed denial of service attack (DDoS) targeted at one of their other customers, overwhelming their core network routers. This resulted in many people being unable to connect to our network during this period.
The problem has been resolved (the provider has blocked the attack), and they tell us it should not recur. We sincerely apologize for the inconvenience this caused.
There’s been a lot of talk in the last few days about a nasty PHP security bug that allows “hackers” to compromise some Web sites that use the PHP scripting language.
Our customers are not vulnerable to this problem because of the way PHP is set up on our servers. You don’t need to worry about it.

Between 1:53 AM Pacific time and 2:09 AM on May 1, the disk load on the “web11” server became very slow, requiring that server to be restarted. We did so, and normal service was resumed at 2:10 AM. Other servers were not affected.
