I have had this problem for a long time now and have tried to communicate with Ucoz via email. They have ignored the latest email but on previous occasions they have responded and have fixed the problem, only for it to return again.
I have two sites:
Initially, I lost access to "shadowsworkout" but after emailing Ucoz, it became available again.
Now I can't get to the "speakfreely" site.
There are some interesting facts here:
1) Using TRACERT it is obvious that the messages are always blocked at the "steadfast....telia.net" address. This was confirmed for me by looking at the the TRACERT outputs shown on this thread and other similar threads. Clearly, this is where the root of the problem lies. Other routers on the way have no problem relaying the message. It is probably significant that the very next router following the telia.net address is Ucoz itself.
2) My ISP is AOL in the UK. If I use IE7 or Firefox I get the access blocked at the "steadfast....telia.net" address. However, using AOL it is also possible to use AOL's own browser (based on IE). Strangely I CAN get access to both my sites using this browser. This suggests that the message from the AOL browser is taking a different route, possibly bypassing the "steadfast....telia.net" address.
Please, Ucoz, give me access to www.speakfreely.ucoz.com again
After all, I created the site and I should have access to it surely
