Email connectivity issues (homiemail-sub4) (RESOLVED)

Posted (July 30th, 2015 at 8:36 am PST) by chalise

We are currently investigating connectivity issues on our homiemail-sub4 mail cluster. This is affecting POP3, IMAP, and SMTP connections. Our team is hard at work looking into this, and we will post more information as we have it. Thank you very much for your patience and understanding!

Early this morning, sometime around 8:30am, we started receiving reports of performance degradation on our homiemail-sub4 email cluster. This degradation was primarily caused by an extremely distributed DoS attack.

Our mitigation service kicked in and started blocking various traffic; the traffic block was mitigated to make sure that valid traffic went through around 9am. The attack continued, and is still ongoing at this moment, and at 12pm our provider decided to turned off our port for about 30-90 seconds.

Our team is currently blocking part of the attack right now, in attempt to help resolve the long standing issue. Unfortunately, due to the scale of this attack, this is a long and ongoing process.

Update 2:00pm PDT: We are happy to announce that this matter is fully resolved. Thank you, once more, for your patience while we worked to bring this issue to a full resolution. If you are still experiencing problems connecting to email (or any other DreamHost service), it is not likely related to this, so please do not hesitate to contact support via your DreamHost panel under Support / Contact Support, here.

WordPress 4.2.3 Security Release

Posted (July 23rd, 2015 at 8:08 am PST) by Mika E.

While WordPress 4.3 is due out in August (Beta 4 came out yesterday, developers please test your themes and plugins if you haven’t yet), this morning version 4.2.3 was released.

WordPress 4.2.3 corrects a cross-site-scripting bug that would allow people with the user role of Contributor or Author to compromise a site. If you have a site with multiple users, this patch is exceptionally important. There was also a bug where Subscribers could make a draft post using Quick Draft, but thankfully not post it. That too was fixed.

All in all, 20 bugs from 4.2 were squashed, 2 security holes were fixed, and just over 50 files were edited. You can read the full release on WordPress.org for the full details.

WordPress 4.2.2, 4.1.5, 4.0.5, 3.9.7, 3.8.9, and 3.7.9 will all roll out to users via the WordPress.org auto-update system. Remember, this is something that runs outside of our One-Click installer updates. If you’ve got WordPress on, it’ll run.

If you’re running a super old (pre-3.7) version of WordPress and you haven’t upgraded yet, please invest the time and effort. Trust me, it’s not safe. And while WordPress does perform it’s own awesome auto-updates for security releases, please make sure to update any sites you host anywhere else, or that don’t use our One Click, or where you’ve turned off the security updates.

Mail Connectivity Issues (RESOLVED)

Posted (July 6th, 2015 at 9:52 am PST) by chalise

We are currently investigating issues with email logins. This seems to be affecting IMAP, SMTP, and webmail logins across all our email clusters. Our team is working on this and we will update as more news becomes available.

Thank you for your patience!

Update July 6, 2015 10:25am PDT: It looks like this was caused by a few issues with one of our databases that handles mail authentications (which is why IMAP, SMTP, and webmail were all affected). This has now been resolved and all email should be working normally now. Thanks again for your patience while we got this up and running again!


 

Update July 6, 2015 10:15am PDT: All services should be working again now. We are still gathering information as to the exact nature of the issues and will post more information shortly!

Scheduled DreamCompute Maintenance – June 23rd 10AM PDT (24 hrs) (RESOLVED)

Posted (June 16th, 2015 at 9:20 pm PST) by Justin@DH

On Tuesday June 23rd starting at 10AM, we will be upgrading Ceph, the underlying storage system of DreamCompute, to the “Firefly” release. The new release provides improved performance, faster recovery times in the event of disk replacements, and fixes numerous bugs. We expect the upgrade process to last only a few hours but, given the magnitude of the upgrade, we have extended the maintenance window to a full day to provide ample time for monitoring and tuning. During the maintenance window, you may experience periodic disk I/O pauses causing intermittent availability.

We will closely monitor the maintenance and will be posting periodic updates. This maintenance only affects DreamCompute.

If you have any questions or concerns, please don’t hesitate to contact support for assistance.

Update June 24, 2015 10:00am PDT: The maintenance window is now closed. The Ceph upgrade was successful and we are already seeing increased stability from this. If you notice any issues post-maintenance, please contact support.

Posted (June 16th, 2015 at 9:19 pm PST) by Justin@DH

On Thursday June 18th starting at 7AM, we will be updating DreamCompute to add live migration functionality. This will allow us to perform maintenance and upgrades to the underlying hypervisor hardware with minimal disruption to your virtual machines. To complete the process, we’ll have to reboot your virtual machine. While the reboots are scheduled to occur throughout the day on Thursday, when it is your VM’s turn to be rebooted, it will only take a few minutes to complete. Your VM will be temporarily unavailable while it’s rebooted.

We will closely monitor the maintenance and will be posting periodic updates. This maintenance only affects DreamCompute.

If you have any questions or concerns, please don’t hesitate to contact support for assistance.

Update June 18, 2015 2:00pm PDT: All 42 hypervisors and the instances on them have been upgraded and restarted. We checked the status of instances running and don’t see any unexpected results at this time. If you do see any issues with your instances after this maintenance, please contact support.
