dev.getsol.us down - 502 Bad Gateway

palto42

Just pushed an update for a patch with arc diff to D10917 which failed with an exception:

$ arc diff
Linting...
No lint engine configured for this project.
Running unit tests...
No unit test engine is configured for this project.
 Exception 
[HTTP/502]

(Run with `--trace` for a full exception trace.)

As I wanted to check the status on the webpage, I found that https://dev.getsol.us/ is always responding with "502 Bad Gateway" now.

Did my arc diff crashed the server or did I got the exception because the server went down?

Sorry, we were performing some maintenance briefly. No worries.

@DataDrake No worries & thanks for reviewing and accepting my patches 🙂
Another thing I noticed on https://dev.getsol.us is that I don't seem to get notification emails for my subscriptions. For example I didn't get any notifications for the recent comments you added on D10917 although I'm automatically subscribed.
But if I create a new task, then I get an email notification (which is not really necessary), so the email basically works.
I checked the settings, in the "Email delivery" the setting are "Default" and in "Email preferences" all is set to "Email". Did I miss anything, is this a bug or expected behaviour?

Your provider is likely just blocking an I.P. used by SendGrid. @livingsilver94 has been having the same issue. Nothing we can do on our end.

JoshStrobl The strange thing is that I get the notification email if I create a new task or on some comments like in T8260 but not for the patches it seems. But you are right, my email provider is quite strict with blocking anything which might be spam.
Anyway, I'll check my open patches from time to time to ensure I don't miss something 😀

palto42 Check your notification settings in Phab.

palto42 Do you not have the option to have spam delivered to a specific folder instead of just being outright blocked? If not, I'd look for another provider or complain loudly to your provider that legitimate email is being blocked as spam.

If you're interested in looking at another provider, I highly recommend Fastmail. The service is not free, but the cost is reasonable in my opinion. I've used them for at least 10 years now and love the service; multiple email aliases; some online storage; notes; calendaring; write your own rules; email addresses that can't be replied to; etc.

@DataDrake I already double checked the settings on https://dev.getsol.us in the sections "Email Delivery" and "Email Preferences", is there any other place I should check?
@downhill I had already changed my email provider settings to deliver mails which the text analysis declares as spam to a dedicated folder. All other kind of spam i(e.g. based on black list) is rejected. Since I get some notifications, I don't think that the server is generally blocked, but I also don't get notifications into the spam folder.

I have now changed my primary email on https://dev.getsol.us to another provider to see if this helps. If it solved the issue, I know that my main email provider is causing the issue (blocks too much).

palto42 It would be the Email Preferences for Differential Revisions though those will get you the fire-hose of all emails from Differential.
