withgusto ZNC Migration (3/18/16, 9 PM - 12 AM EDT)
EDIT: Important ZNC Form! (http://goo.gl/forms/FehgMfKMp5)
As you may have heard (http://ourl.ca/22302/), withgusto is undergoing a major downsizing to ensure viability in the future. As part of this plan, we are moving ZNC to a different, separate server to allow ZNC to operate independently of withgusto's main server, hopefully increasing the stability of both for times to come.
What does this mean for you?
- There will be downtime for around three hours from 9:00 PM - 11:59 PM EDT this Friday, March 18th, 2016. ZNC will be completely disconnecting during this time. The downtime may be shorter depending on how things go, but don't count on it! If you maintain ops yourself, you should make sure to log in manually to keep ops during this time.
- RDNS will be changed around 5 PM EDT this Friday, March 18th, 2016. Avoid reconnecting to IRC from ZNC during this time if you depend on hostname recognition!
- After the move, your account and quality of service will NOT be affected. (In fact, we hope that it is MUCH better!)
- We will be changing the login server once more. The hostname should stay the same - znc.withg.org. The only thing that will change is how you access ZNC. If you signed up on the form (http://goo.gl/forms/FehgMfKMp5) below, you will get an email soon on the change in login server. Please keep it private!
- Since the ZNC service is essentially segregating from withgusto, we want to get user data with this survey (http://goo.gl/forms/FehgMfKMp5)! Please fill it out ASAP: http://goo.gl/forms/FehgMfKMp5
- We will update everyone if there are any changes to this plan, as well as during and after the migration.
We apologize for this downtime, and as always, we thank you for flying withgusto! ✈
If you have any questions, comments, or concerns, feel free to ask away in this thread!
Updates:
- [3/18/2016 10:14 AM] We will be changing the login server once more. If you signed up on the form (http://goo.gl/forms/FehgMfKMp5) above, you will get an email soon on the change in login server. Please keep it private!
- [3/18/2016 10:14 AM] All preparations have been made for the move. Please get ready for the switch as soon as possible.
- [3/18/2016 8:36 PM] Migration will occur in less than 30 minutes! Please backup ops for your channel, and get ready for the switch! Remember, the service will be down for around 3 hours, or until things are completely set up!

withgusto ZNC Migration Complete!
Thanks to everyone for their patience. We have now successfully migrated from our old server to this shiny new one!
- You can still connect with the old server name, without any configuration changes. You can use the alternative server name if you are having issues.
- The web interface is now only accessible via the new URL (sent via email). No more ports needed! This should help with any firewalls preventing you from getting out.
- We have changed the SSL certificate from withg.org's ComodoSSL to the new Let's Encrypt! The old SSL certificates tend to cost around $10/year... why pay that when you can get it for free? :D
- There's a custom renewal system in place for Let's Encrypt - the regular one is a bit memory heavy daemon-wise, and we only have 128 MBs of RAM on this server!
- We decided to use https://github.com/diafygi/acme-tiny in place of that, along with a custom setup to update the certs for both our web server and ZNC. This is something I've been working on as an experiment on a cheap, smaller VPS, and so far it has been working well on that one - Let's Encrypt on a 64 MB VPS!
- That said, despite testing, things can always still break in the future - please let us know if you have any problems with connecting to ZNC!
- In addition, we have upgraded all of our SSL to super strength (A+ on the SSL test (https://www.ssllabs.com/ssltest/analyze.html?d=znc.withg.org&hideResults=on&latest))! We figured that if we have time to migrate, we should have time to do security right!
- Beyond that, we also enabled Cloudflare SSL. However, with the free Cloudflare SSL, this comes at a cost - IE on Windows XP will no longer be supported. Specifically, SNI support is not available at all on Windows XP via IE. However, if you are on Windows XP, using Firefox or Chrome will still work. Those browsers do not use Windows XP APIs, and bundle their own support for SNI. To say that again - if you are on Windows XP, just use Firefox/Chrome and things will work! If you must use IE on Windows XP for whatever reason, please let me know. If there is a serious need, I may be able to set something up for you!
- Internally, logs have been converted to the new directory-based structure (http://wiki.znc.in/Log#Arguments). It used to be all stored in one directory, resulting in thousands and thousands of files (and slowness)! For currently active users, this has been reorganized - you do not have to do anything on your part. In the future, we may be using this new structure for some potential new ZNC features down the road... stay tuned!
- This time around, we're hoping for much better uptime! From initial impressions, ZNC seems to be faster at connecting to IRC, and most (if not all) of the BindHosts are resolving correctly. In addition, since this server is separate from the main one, uptime should hopefully be better - less impact from other people on the server! (In fact, the only person on this server is me!)
- Enough technical stuff. Finally, we have some awesome new hostnames available for the picking! (Totally not inspired from rcfreak0! :P)
Here is the list:
znc.withg.org
team.windows.znc.withg.org
team.linux.znc.withg.org
team.mac.znc.withg.org
fancy.schmancy.znc.withg.org
powered.by.the.amazing.znc.withg.org
dont.look.behind.this.znc.withg.org
food.for.thought.znc.withg.org
yum.znc.withg.org
sparkles.znc.withg.org
Under your user settings, simply change your BindHost to your favorite, then click Save at the bottom. You can also change this per network if you want different hostnames on different networks. - znc-push (https://github.com/jreese/znc-push) has also been installed. If you have PushBullet (or some other push messaging app), and you want notifications whenever someone on IRC highlights you or PMs you, this is for you! (It basically allows you to get important notifications from IRC on your phone, desktop, etc.)
- That's it! If you haven't already, and you are a ZNC user, please fill this out: http://goo.gl/forms/VFvTjFVpke
