Yes, I have. It was anyone.

I haven't had the problem lately. Hesitate to post that. Would be nice if someone from Fastmail said either

We know / think we know what was / is wrong and it's fixed / we're working on it ...

OR

We don't believe there's a problem (and aren't looking to resolve it)

Transparency about problems was one of the things that was attractive about Fastmail in the early days and helped made the glitches sufferable.

Transparency and customer focus were a large part of what originally attracted me. In fairness, while most FastMail staff are not as open as they used to be, they do still tend to thoroughly and truthfully explain major issues that affect large numbers of users. The loss of customer focus, and retreat into their ivory tower is a bigger concern.

Wondering what the packet loss to fastmail is for the folks experiencing the problem.

Network speed and packet loss are separate metrics. And the latter is far more relevant to the reported issue.

For me: (I'd suggest folks let it run for at least a few minutes to get a decent sample.)

I've never seen anything other than 0% packet loss.

What program did you use to generate the output? (I don't recognise it)

I'm using mtr. What are you using?

http://www.bitwizard.nl/mtr/ or use your favorite installer; it's probably supported (homebrew, port, etc.)

So far just ping and traceroute (on linux). I didn't know about mtr (thanks); turns out I have mtr-tiny installed (on Linux Mint).

I've left it running for a while. No packet losses at all between me and Fastmail.

Any problems yet with the new interface during this period of no packet loss?

Yes. The new UI hung on me this morning when I reply on a message with an attachment. I checked the link to mail.messagingengine.com at the time: zero packet loss and 115ms response times.

Hmm... I'd post or share mtr output like I did as part of a detailed issue report and press support to look into it. Sometimes they miss threads here. What city/area are you in? Your OS and browser are? otherwise working well? :confused:

OS and browser:

I have the same issue with both browsers (Chrome and Firefox) and both OSes that I use (Windows 7 and Linux Mint).

Currently I'm in the countryside in County Wicklow in Ireland connected via a 3Mb DSL connection with a 270k uplink.

I hit forward on a message with a 401k attachment just now and Fastmail died, as it often does when I do that. I had to log out, log back in, download the attachment, compose new, then attach the attachment.

It's been like this for a long time. Never happened once with the old UI.

Be sure to file a support request.

My reply mail has been sticking for me today, I wonder if fastmail are changing over servers or backing something up.

The problem is only when I hit reply my normal compose mail goes ok.

I have POP access enabled and I wonder if deleting my read mail in Thunderbird is breaking something in fastmail, although I have ticked leave mail on the server, a few weeks ago some of my mail was missing in my fastmail in box, but the last 3 or 4 weeks it seems to have sorted its self out and all my mail is being left on the server.

Update, it did it again today and the reply I was sending had lots of smilies so perhaps there is something in Fastmail that does not like smilies or photo's....:D:D:D

I continue to have the problem intermittently. I doubt it's connected with smilies. In my case it happens only when there's an attachment. If there are several it's almost guaranteed to happen -- it means I have to save and recompose every time instead of forwarding.
