Web interface intermittently very slow

akorvemaker · 15 Feb 2017, 05:18 AM

For the last 2-3 weeks I've found the web interface to be occasionally very slow. Painfully slow. Sometimes hitting refresh will fix it, at least for a while, but not always.

For example, I'll click on an email message and wait 20-60 seconds for it to load. The top email headers portion will sometimes load, but the email body will just say "Loading...". If I hit refresh, it usually works and functions for a while, but eventually (sometimes within the hour, sometimes after a few hours, sometimes the next day) I have the problem again.

As another example, I'll hit reply and end up with a blank FM screen .(I think there's the sidebar and the header bar, with the rotating "loading" circle in the middle. I think that's how it looked...)

It's happened enough, quite frequently over the last few weeks, that it's not just a random glitch, and it doesn't seem to be going away on its own.

And most of the time it runs perfectly quickly, like I'm used to.

I haven't found a pattern, though going into messages to read them or replying to messages seem to be the most common things I recall encountering.

I'm running Chrome on Windows 10.

Any thoughts? Anyone else having similar problems?

For example, I just tried to reply to a message and got this for about 15 seconds:

Need regulary to restart the app on Android because of these blue blocks.

It is probable that the cause is an unstable network link between you and New York Internet. The FastMail Pingdom report shows nothing unusual, and a general problem (even one affecting a single server) would not go unnoticed for long. I would try to do some network debugging (perhaps, with a traceroute command) the next time this hits.

I was also having same problem since few weeks. I am using Safari on Mac Book Pro. My problem did not only stoped here, when Fastmail web page was open all (any open) tabs reacted slowly. If I closed Fastmail web page tab everything used to become normal.

Since 2 days though everything seems back to normal. Hope it stays this way.

Note: I was getting same behaviour using Chrome on Mac Book.

I can try to do that. The only website I'm noticing issues with is FM. Other sites still respond promptly while I'm having these issues with FM.

That has been reported before. There are two aspects that are likely involved. First, depending on your location, it is very common that a specific network route has an issue (causing problems with a small number of sites) but most network activity continues to be OK. Second, the characteristics of FastMail's current interface make it susceptible to problems with a small number of lost packets. Asynchronous page loading can easily be broken in ways that are difficult to detect and recover from. The behavior you describe suggests the problem is probably not with your local network, or directly with your ISP, but with a network link between your ISP and NYI. This conclusion is only very tentative.

Thanks for the tips. I'll see if I can find a little more info next time it happens.
