Hi Nick,
Just to be complete for future reference as I had not heard of it before
and I can see it happening to other HOT mapping groups in the future:
We think this is not related to HOT or the Tasking Manager.
We suspect that it is related to OpenStreetMap in general and the
process of downloading the already existing data from OSM to your local
users.
Althio was suggesting you speak to the OSM system administrators via the
general OSM email lists or IRC.
It looks like you might have already followed up in IRC or someone with
the same problem did and the edited exchange is below.
===============================================
<User> we were able to load our imagery and save data into OSM, but were
unable to download the existing data into the editor. I looked at the
network logs and everything was coming up 509 bandwidth exceeded
<User> it subsided later, but would come back, sort of like we were
getting throttled access.
<OSMSysAdmin> you just need to shout on here with your IP address and we
can apply a temporary fix
<OSMSysAdmin> unfortunately there is no way to "book" the fix in advance
- it has to be applied at the time that the problem occurs
<OSMSysAdmin> and yes throttling is exactly what is going on
<User> ok, in 12 hours from now can I do a ping? or does it gradually go
back to normal?
<OSMSysAdmin> it caps you to about 100Kbyte/second with a maximum debt
of 250Mbytes - once you have downloaded 250Mbytes downloads will be
blocked but that debt will decay away at 100Kbyte/second so yes, it will
go back to normal over time once you stop
<OSMSysAdmin> it should only take about 45 minutes to clear if you stop
completely
<User> the venue might have a limited number of IP addresses which could
be behind the problem
<OSMSysAdmin> the limit is per address so if it is natting or proxying
people then that is likely the issue
<User> I'll pop back onto #osm-dev in the morning and have our IP
addresses ready in case anything happens
<User> ok this is all good to know. I wasn't aware this could happen
with normal editing, but I guess we have a good number of people and
some dense data already uploaded into the system
=====================================================

Hi Nicholas,
I would say the general mailing list 'talk' or the technical working
group may be better suited than the HOT list for your request.
See also:

"To avoid having your access blocked, please discuss your requirement
with system administrators either via their wiki pages or on the IRC
channel prior to starting."

Apart from that, some free and unchecked advice:
- consider offline editor JOSM
- use iD with zoom close in, not downloading large areas
Best of luck.

Hi,
I'm working with The Asia Foundation to run an OpenStreetMap map-a-thon in
Ulaanbaatar, Mongolia. We have 17 teams of 3 people, mostly students and
city planners, mapping unplanned areas of the city (ger districts)
At 3:30pm local time, we got a 509 Bandwidth Exceeded error on most teams'
machines, so we had to end our first day early. No one's data is lost, but
we can't download existing data into iD, so every map area looks blank.
There was a risk we would add the same building many times.
Is there a way for us to re-enabling editing before tomorrow morning? And
keep the gates open for another 48 hours or so?
I'll do my part by closing a couple of apps (including Show Me The Way from
OSM Labs) which were running at the time
Regards,
Nick Doiron
