The website appears to be back on its feet today, but yesterday there were all sorts of issues - they obviously changed something, but not in a good way.

PHP code is normally executed on the server. All you should see is the output from running the code, not the source code itself. It sounds as if your copies of Opera and Edge contacted the server in question at a time when the PHP interpreter was not fully active, and had cached the resulting response for that url. Yes, a thorough cache reset is the appropriate remedy.

Strangely, it's not on the list here: https://boinc.berkeley.edu/projects.php and half of my computers list it as a project I can attach to, and the other half don't. Is there a problem with Boinc getting updated project lists?

There's a curious, undocumented, but deliberate design choice in BOINC. If you set the configuration flag 'dont_contact_ref_site' - if, for example, you've got better ways of diagnosing the health of your internet connection - then the periodic update of all_projects_list is also supressed.

LHC tasks are going to be in short supply (or non-existent) for a bit, they are doing some updates:

CMS wants to upgrade WMAgent to bring in a new version of CouchDB. I've just submitted a new workflow which should start draining around midnight Sunday (European). Please be ready to set NoNewTasks late Sunday to avoid any problems. Hopefully we'll be up again by Monday night.

This affects only CMS.
Theory and ATLAS are available as usual.

Why do projects often ask us to set no new tasks? Surely they can just turn off the server tap?

Because if you don't turn off work fetch, your client will keep pestering their server with "Is there any more yet?" requests.

Unlike us, they probably have to pay for their own bandwidth. It's easier, simpler, and more polite if we just shut up for the duration.

And some volunteers write scripts that request work every few seconds, so that they're first in line when work does become available.

Update:
A few CMS tasks are now escaping into the wild.
It will probably take things a bit of time to get back to normal (whatever that may be).

Dear Volunteers, we are thrilled to announce that our website and forums have finished rebuilding and testing, and are both available for public access.

... iThena Measurements down for 12 hours. And before that server disks were full for 2(3?) days so no uploads...

Wery poorly maintained project.

* iThena Measurements project went offline / unreachable some time in last 8 to 9 hours after about 2 1/2 days of server disk full.

Won't be holding my breath that a permanent fix will ever be implemented. LOL

Aaand no big surprise: iThena is down again...

BOTH iThena Measurements (NCI) and it's companion project iThena Computational (CPU) have had the BOINC SERVERS off-line since 2022-06-28... almost 5 day now.
