Seeing warnings about an expired SSL certificate?

If you’re seeing warnings in your web browser or mail program saying that an SSL certificate has expired (whether it’s for our tigertech.net site, for a site we host, or for millions of other sites completely unrelated to us, like dictionary.com), that’s happening because a “root” SSL certificate distributed as part of your computer operating system has expired.

This can happen if you’re using a computer or program that hasn’t been updated for at least five years (that’s when Microsoft, Apple and others started providing replacement certificates with their updates).

There are many pages online that talk about this in technical terms (here and here, for example), but the short answer to “how do I fix this” is to update your computer operating system if you can. That will fix everything.

If you can’t update your computer, you can use a recent version of the Mozilla Firefox web browser to avoid the problem when viewing websites. That works because Firefox includes its own updated root SSL certificates, instead of using the outdated ones that came with your computer and haven’t been updated.

If you’re using an old version of a mail program that shows an error, it may allow you to add an “exception” or check a box telling it to always trust the certificate anyway — it might look like this if you show the certificate details, for example:

If it doesn’t allow that, you can either disable SSL in the settings of that mail program (for example, by unchecking the “Use SSL” checkbox in older versions of Apple Mail), or you can use the Firefox web browser to read your mail using webmail. If you’re one of our customers, that’s at webmail.tigertech.net.

MariaDB (MySQL) database server update from 10.3 to 10.5

Over the next three weeks, we’ll be updating the MariaDB (MySQL) database server software on all our servers from the MariaDB 10.3 series to the MariaDB 10.5 series (equivalent to the Oracle MySQL 8.0 series).

The MariaDB/MySQL database stores pages for WordPress and other sites that are run by scripts. Customers should not notice any difference after this change; we’re upgrading it to a more recent version simply to make sure it’s as fast, reliable and secure as possible. We’ve been using the new version on internal and test servers for some time.

At the moment the software is updated on a server, WordPress and other database-backed sites on that server will have 30-60 seconds of unavoidable “downtime”. To minimize the impact of that, we do these upgrades only on Friday, Saturday and Sunday nights between 9 PM and midnight Pacific time (midnight-3 AM Eastern time). We expect this process to be complete on all servers by September 6.

Beyond that one-time brief interruption in service, customers should not notice any difference to how their site works, as we said. But as always, don’t hesitate to contact us if you have any trouble or questions.

Update 9:24 PM Pacific time September 5: This upgrade has been completed on all servers.

Brief scheduled maintenance July 16, 2021

Between 10:00 PM and 11:59 PM Pacific time on Friday, July 16, each of our hosting servers will be restarted. This will cause a brief interruption of service (less than 5 minutes) for each site at some point during this 2 hour period.

Upgrading to Debian 10 “buster” (complete)

We’re upgrading our servers from Debian Linux version 9 (codename “stretch”) to version 10 (codename “buster”). We’ll be finishing that process over the next couple of weeks.

Your website and email should continue working as they always have, and we don’t expect any downtime. However, if you do have any trouble, don’t hesitate to contact us.

Although the final steps of the upgrade modify hundreds of software packages on the server, we’ve tested it extensively and don’t expect most customers to notice any change. (We’ve already been using the newer version of Debian for our own servers.)

Having trouble sending to Gmail? (resolved)

If you’ve had trouble sending to Gmail addresses today or yesterday (December 14 or 15), where an address that you know is valid bounces back with “The email account that you tried to reach does not exist”, the problem isn’t you, or us. Gmail had a problem that caused this for all senders, seen on their status pages yesterday and today, with the latter confirming “Affected users received a bounce notification with the error “The email account that you tried to reach does not exist” after sending an email to addresses ending in @gmail.com”.

They also confirmed it on Twitter:

They say the problem is resolved now, so if it happened to you, it should work if you try sending again.

Webmail 2020 is now the default

For the last few months, we’ve had a new webmail interface available for our customers, but we hadn’t yet made it the default if you click “Webmail” at the top of our pages.

Starting today, the new interface is the default when you click that link. If you don’t like the new webmail system for some reason, the old webmail system is also still available from a link on the new login screen (and will remain available for the foreseeable future).

We have some tips for using the new system, which has more flexible message composing, the ability to drag-and-drop images and other attachments, a simpler mobile interface, and a generally more modern feel.

Updated version of webmail 2020

For the last few months, we’ve been publicly testing a new webmail interface for our customers. The new system has more flexible message composing, the ability to drag-and-drop images and other attachments, a simpler mobile interface, and a generally more modern feel.

Today, we’ve updated the software to (among other changes) add a new “Dark” theme you can choose, and also to improve the message view in “two column” layout. You can now switch between a “split” and a “full height” view by clicking the new zoom icon (shown here circled in green):

Split view
Full-height view

You can find the new webmail interface at https://webmail.tigertech.net/, and we have some tips for using it. (By the way, if you don’t see the new features immediately, you may need to logout and login again, or clear the cache in your web browser.)

We intend to make the new interface the default soon. But if you don’t like the new webmail system for some reason, the old webmail system is also still available (and will remain available for the foreseeable future).

Microsoft Outlook crashing?

Is your copy of Microsoft Outlook crashing when you start it today? If so, it’s not just you, and it’s not a problem on our end. It’s a bug in the latest Outlook update that Microsoft is aware of:

This page at Bleeping Computer describes how you can switch back to an older version, and you can also use our Webmail pages to read your email if you need to.

MariaDB (MySQL) database server update from 10.1 to 10.3

Update 9:16 PM June 27: the maintenance described below has been completed on all servers, so all servers are now running the MariaDB 10.3 series.

Over the next three weeks, we’ll be updating the MariaDB (MySQL) database server software on all our servers from the MariaDB 10.1 series to the MariaDB 10.3 series (equivalent to the Oracle MySQL 5.7 series).

The MariaDB/MySQL database software is what stores pages for WordPress and other sites that are run by scripts. Customers should not notice any difference after this change; we’re upgrading it to a more recent version simply to make sure it’s as fast, reliable and secure as possible.

Mailman mailing list software upgraded to version 2.1.30

The authors of the Mailman mailing list software we provide for customers have recently released version 2.1.30 to fix several bugs.

We’ve upgraded the Mailman software on our servers as a result.

Users of Mailman lists shouldn’t notice any changes, but as always, don’t hesitate to contact us if you have any questions or see any problems.
