Our business offices will be closed on Monday, May 27 to observe the US legal holiday. As always, we’ll provide same-day support for time-sensitive issues via our ticket and e-mail systems. However, questions that aren’t time-sensitive (including most billing matters) may not be answered until the next day, and telephone support (via callbacks) will be available only for urgent problems.
Between 10:00 PM and 10:59 PM Pacific time Wednesday May 22, 2013, the “web05” and “web07” servers will be restarted. This will cause an eight minute interruption of service for each server at some point during this hour.
The PHP developers have announced the release of versions 5.3.25 and 5.4.15 that fix several bugs. We’ve upgraded PHP 5.3 and 5.4 on our servers as a result.
We’ve also updated the ionCube Loader PHP extension (which most of our customers don’t use) from version 4.2.2 to version 4.4.0.
These changes should be transparent to customers. In the unlikely event you experience any issues, don’t hesitate to let us know.
The “web04” server experienced extremely high load for several minutes beginning at 8:00 AM Pacific time on May 9. Sites on this server were slow or unavailable as a result.
Several people have asked us about the recent WordPress WP Super Cache and W3 Total Cache plugin security vulnerability.
For the most part, sites hosted on our servers aren’t vulnerable to this because we block comments that contain the malicious code.
We’ve talked before about WordPress login rate limiting. Attempts to guess WordPress administrator passwords are an ongoing problem, getting worse all the time.
The average WordPress site we host has received tens of thousands of malicious login attempts this month, with hundreds of thousands of different IP addresses being used in the attacks. We try to block the IP addresses that are responsible, but the ever increasing number of addresses means we can’t block all of them — an individual address often attempts a login only once a day for a given site. We need to adopt other tactics.
1:31 PM Pacific time: Our technicians are investigating high load and slow page load times on the “web04” server.
2:09 PM Pacific time: This is being caused by a distributed denial of service attack on WordPress sites that is causing outages for many companies. We’re working to block it.
Between 12:50 and 1:23 PM Pacific time, service was intermittently unavailable or slow for sites and e-mail on the web12 server. In addition, customers on other servers may have seen brief delays or high load for about two minutes during this period.
Between 11:04 PM and 11:44 PM March 23, our network was either slow to respond due to high packet loss or completely unavailable to some customers.
The PHP developers have announced the release of version 5.3.22 that fixes several bugs. We’ve upgraded PHP 5.3.21 to version 5.3.22 on our servers as a result.
In addition, we now offer PHP version 5.4.12 as an optional choice in our control panel. For now, the PHP 5.4 series is recommended only for customers who need to test “cutting edge” features. Most customers should stick with the PHP 5.3 series, which is compatible with a wider variety of scripts.
